  11. M***v



  12. V***v

    Ordered at night, in the morning already sent. It took 10 days to Moscow. Super! The box is foam, the device itself is of excellent quality, in addition a bunch of everything. Measures very accurately if measures, but there is something that it can not check. These are many MOSFET field transistors. This is logical, because not all can be forced to work on such a device, and especially to determine them. Especially high voltage. They need a special device.


  13. V***o

    Sent quickly. Delivery to Rostov region about 3 weeks. Packed very well, in foam box. Everything came without damage. Included calibrated. Checked only on capacitors, measures correctly. The only thing that the battery is small capacity, it does not work for long, in the future I will find another. And so in principle satisfied. I recommend.

    Good works very well recommend to everyone


  31. Customer

    Arrived, works amazing, has an integrated rechargeable battery. Very great device


  32. A***n

    Works, measures. I do not understand why the people complain about the small capacity of the battery! You with him in the taiga or to go! But the fact that the battery is charged to 3.7 V with the maximum possible 4.2 V-Jamb, it is necessary to modify.


  33. V***V

    Hello, everybody. The order was made on October 30, received on November 23. The quality of the device is excellent. I took it not myself, so as the parcel came I could not take a photo and immediately gave it to people. The answer came that everything is fine! The device T7 is much better than the device T4, said gives more readings than T4.


  34. V***V

    Everything is fine as in YouTube watch? v = vm5xfwagc6m. (moped is not mine). Only ukkum on 350 mAh. Shipping 20 days.


  35. E***v

    The thing is useful, came pretty quickly. Everything works as it should. Hesitated transistors to call the tester. All radio fans strongly recommend this device to significantly accelerate the defects of the elements.


  36. A***n

    The tester is just a miracle, everything itself measures, the battery charged is installed. In Podolsk 3 weeks goes, tolerable. I recommend to every electronics!


  37. N***v

    Very useful thing! Delivery to Rostov very quickly!


  38. A***r

    Everything works fine


  39. A***n

    Delivery 3 weeks. Track tracked. The parcel moved through Finland. The device is well packed in a foam box, in working order and fully corresponds to the description. Seller-I recommend!

    Everything is fine. It came relatively quickly in the Urals-20 days. The tester works. Packing is molded. Thank you


  43. M***d

    every thing is fine, only the IR facing difficulties sometimes work others not


  44. A***N

    Order in Voronezh came in 25 days, everything works. Slightly moves when measuring the capacitance of capacitors. But not critical. Seller recommend.


  45. Customer



  46. Customer

    Everything is fine, works well

    Thing for life! Simple and stylish!


  49. I***n

    Got the device, for its price category I would say perfectly!


  50. K***b

    Thanks on Aliexpress time


  51. N***v

    I’m not like a professional satisfied with taking for minor repair of household appliances addition to the usual tester that could check in the fault of OK


  52. U***r

    As described, fully working.


  53. A***n

    Order sent by store quickly. Packaging is a reliable foam box. The device itself has slightly more functions (checking infrared panels and checking the stabilitrons up to 30 V) than a cheap non-Hull tester. Plus lithium battery. But sits right in front of her eyes. After fully charged at a time, it seizes to 3,7 V. Maybe I just got such a defective battery. The codes of the remote from the TV Samsung recognizes once for 20. From the amplifier Yamaha from the first time. In the reviews on YouTube do not respond very well about it. Plus custom firmware expanding its functions, there is no network. In general, its pros is only the case and lithium battery. Minus for me-small inscriptions on the screen.


  54. A***h

    Very good quality, nice plastic, works as expected, recommend this store


  55. A***H

    Great thing. Everything works. Came quickly.

  64. V***h

    Came all in excellent packaging, fast enough, + a small gift!


  65. V***v

    It works its functions but the battery I think is weak only 350 mahs need more.


  66. F***t

    Excellent product. Works perfectly. Well packed. Delivered at home without additional fees.


  67. S***n

    Corresponds to the description, works


  68. R***n

    great product


  70. I***V

    It came fast enough. Packed in foam box. Works great.


  71. V***o

    Delivered to 4 of 5, a little crumpled packing box. Mail wine, so it’s not important. There are also good fellows in Chinese villages! Pony on the race will stop, in the burning fan will enter! Thank you, Gee!


  72. A***v



  73. C***s

    Fast and very well packaged. Fast & very good packaging.


  74. D***v

    Came packed in a foam box. Everything is safe and sound. Works. I can not comment on the accuracy of measurements yet…


  75. G***r



  76. A***l

    Everything works! Included calibration short, led, capacitor (electrolyte per 10 UF) + charging cable, probes-leads three pieces. Packed-gorgeous! In general I recommend. It’s been a long time.


  77. V***a

    Tester came in 45 days (very long shipping! ). It was still charged, after testing found that the capacity readings were below 20%. Calibration didn’t help. The store is sociable, going to the meeting. After testing the different parts decided to calibrate again directly from the chump from the kit. And then the device showed the correct capacitors capacity. Oben is happy with the purchase. Seller recommend, true shipping is very long, may because of quarantine. True friend ordered from another seller later, and received in 3 weeks.


  78. R***a

    Measures various electronic components quickly!!! Recommend!!!


  79. A***v

    Delivered Ooo very long-more than 70 days. But the device even came discharged but works properly. At least that’s pleasing.


  80. A***o

    Not fast delivery, working, high precision does not claim. The battery is very small, written 350 mA/H, and actually 150. Happy with the purchase. Thank you.


  81. V***a

    Delivery to Moscow for 2 months, but this is all because of the post of Russia, the device came in foam, how to send glass for phones, calibrated, tested three containers, a pair of resistors, works excellent, more plus bonuses, check IR remote control, comfortable pipes with hooks on the springs, I am pleased with everyone except long delivery, I think the quarantine will end and reach everything will be faster, the store is not to blame, so that I advise, and the device, and the seller!


  82. S***i

    thank you, it’s all right! device works as expected.


  83. M***t

    Great Product and great service. would recommend Aliexpress to all my friends. Kind Regards Mike


  84. S***n

    Works. Delivery for a month.


  85. M***n

    Everything is super. Works.


  86. Customer

    Ok. 16 days delivery.


  87. V***t

    Ordered 3 devices .. 2 came, the third lost in the mail. The store tried to solve the problem, then fully refund the money. The first 2 devices work wonderful. Recommend.


  88. A***v

    Good packing. Quality goods.


  89. Customer

    Almost 2 months went to me my parcel, very long as the tester is a good device.


  90. E***v

    The store sent the parcel quickly, but it went almost 2 months. Packing is a rigid foam, and as can be seen from the first photo, it was not superfluous. Inside, everything was in order and in working order.


  91. M***n

    Works like a charm. able to detect various components, like diodes, caps etc. quite a game-changer for the price


  92. A***v

    Great tester.


  93. G***v

    Went for a long time, 47 days, the device is good.


  94. S***v

    Super, with strong temperature changes, calibrate. There is a jumper in the kit. In terms of delivery, it has been exported for a long time


  95. V***v

    Goods received)) not very fast, but I think it all due to quarantine, well packed) the store recommend a very good and responsive person for which he thanks)


  96. P***t

    Fast delivery, super product. Thank you very much.


  97. A***v

    Great device


  98. A***k

    Thank you to the store for honesty. The second parcel received, the tester turned on, everything works


  99. Y***v

    Excellent!!! I do not take for the first time! excellent device!! thank you!


  100. Customer

    I recommend this selling


  101. A***n

    Delivery more than a month in the Rostov region. The product corresponds to the description. Measured a test of about 95% components. Accuracy is sufficient, and, measurement of containers is better than that of a stationary multitester. A rather narrow range of inductance measurement (from 0.02mh), I.E. Measure just the coil for VHF or DMV will not work. Measurement of containers should be carried out without pike-direct connection, otherwise God-free lies (probably, form LC-contour). Badly measures powerful semiconductor, especially, thyristors-defines as a resistor between UE and K, probably, there is not enough capacity to open. Seller and recommend!


  102. V***w

    The device received in the kit packed soundly reached in 59 days of comments no thanks to the store recommend all good luck


  103. T***i

    Very fast shipping!


  104. R***r

    Packed Super. Done well. Works.


  105. V***y

    The store is great. Delivery to Moscow for 21 days. Packed in a dense foam box and bags. Includes test elements, clamps and charging cable. The device is charged. Works fine. Calibrate contacts 1-2-3 before starting work. At 22%, open and wait for 100% (see photo). Product and seller recommend.


  106. S***r

    Got it, it works. Remotes from TV do not all determine, but the IR radiation reacts.


  107. D***n

    Works. It does not quite exactly, but it will go for the touch. Has been selling for a very long time, had to open a dispute, it was sold twice for 10 days, here on the second 10 days and came. It’s convenient that with ACC.


  108. P***i

    Working properly.


  109. A***v

    Great tester! Everything works. Packing is good, drove whole. Thank you for the good product. Upset only long delivery.


  110. A***v

    It’s been a long time since the quarantine. The goods are very cool!


  111. R***r

    The goods took 80 days. But I came., well packed. The store is good, he answered the messages quickly. All as in the picture, have not yet checked. Thank you!


  112. V***v



  113. K***v

    Delivered to Moscow in 25 days (AliExpress standard shipping). Packed in a box. Very compact, nice design. Shows more useful transistor characteristics than the cheaper T4 model (see Photo), because of this and bought. In the complete set of probes with spare legs, a short USB cord for charging, led and capacitor (apparently, for tests). Of the shortcomings-there is no site for testing SMD components.


  114. A***g

    Went to Krasnoyarsk for 2 months! Very long .. Although I ordered AliExpress standard, which is much faster. Came in a foam packaging of excellent quality. The device is completely intact. Tried in work on capacitors, resistors, different transistor (including non-workers), works fine! Excellent thing, I recommend!


  115. A***U

    Is working


  116. V***v



  117. L***h

    Is very good


  118. A***v

    Everything came in time… The only negative-the battery was discharged


  119. R***a

    Incredibly long delivery-3 months,-even by the current standards. During this time, other stores managed to deliver orders 2 times, without problems. Otherwise packed well, the kit, as in the description. Delivered by mail without damage. Instruction on the use of the device is not attached,-the seller believes that the buyer will find everything himself. Strange approach. The device works. However, at a low level of charge behaves as a faulty-the screen begins to flash wildly, there are incomprehensible artifacts, there is no low charge indication. Until I realized, and did not connect the charge, I thought that the tester broke down. In general, while working. Next, let’s see.


  120. V***k

    Came not working


  121. S***v

    Super thank you


  122. A***n

    Everything works, the packaging is good.


  123. T***k

    Super deal, now when analyzing what is what no problem. Resistors measures well, diodes-cool item as the zapomni for what volarz is, and capacitors. More case no sprawdzałem. Recommend to everyone zainteresowanym.


  124. V***v

    It seems to work, compared with the Avometer, on resistors, differences are minimal (tenth OMA). Connected the Conder to 1000 UF, showed almost 1500 UF. The rest of the comparison is impossible. After removing from charging somehow quickly loses the charge from 4.2 V to 3.7 V in a few minutes.


  125. I***h

    all ok


  126. A***n

    All hockey,


  127. A***v

    It’s been 22 days. On the screen under the film is a scratch-0.8x3mm. The button is installed Krivo in the case, and to enable the charge had to be pre-disassembled-the USB connector did not match the hole (((. So it is torn to claim compensation for such cases… conders, resistors, diodes, inductance reads normally. Some transistor problems occur, although a similar device from another store recognizes them. (I wanted autonomous nutrition). From the remotes at hand: Sony,Sharp,Toshiba, “friends” only with the last. It came with a discharged battery. It does not hold for a very long time, but it suits me so far (charging at hand). The device did not live up to expectations, and most importantly-very poor build quality! I do not apply pictures, T. K. The dispute does not open. I will have to believe the curvature of assembly and defects on the word.


  128. I***v

    Shipping fast. The device is good-shows the resistance at the field transistors, measured up to 20 V, too, did not test the remotes. Came charged, I’m very pleased, I recommend the store.


  129. Customer

    Cool tester, I like


  130. A***v

    Delivery to Mo three weeks. The product corresponds to the description. Powerful IGBT transistor for welding shows as capacity. I do not know if the device does not work, or can not.


  131. B***n

    The best packaging that I’ve seen so far. Excellent tester, fast shipping. Thank You.


  132. K***v

    The tester came in a foam box. No damage. The kit is standard. There are no instructions on paper. After charging, the battery did the calibration of the tester and checked its capabilities except for measuring the inductance and voltage of the batteries. The results of measurement of resistance, transistor parameters (bipolar and field), diodes, are close to real. There were questions about measuring containers. T7 does not determine the capacitor with a capacity of 30pf, although the lower limit of measurement is 25pf. Capacities up to 100 UF underwrite by 30-40%, the measurements of the containers above 100 UF shall be placed in tolerances (+/-20%). The store was provided with videos and photos. The seller replied very quickly, professionally and politely. As a result of the negotiations, a solution was found, convenient for both of us. For this I put 5 stars. The seller is reliable and compromises. I recommend to cooperate. T7 tester-lottery. Another time I’ll try to take tc1.


  133. V***v

    Is working


  134. Customer

    Description matches. All basic OK. Стабилитроны measures badly.


  135. S***v

    The parcel is packed perfectly. Cool tester, works as it should.

  139. A***v

    Delivery 3 month, Works, IR codes do not determine in all remotes


  140. A***v

    Works fine. Delivered fast


  141. K***i

    Lowers the voltage of the stabilitons.


  142. I***v

    The tester came to zero discharged. CUM is likely to be replaced. Sorry no instructions. It’s good that there’s a manual on the Internet. After the first start, be sure to calibrate. Especially if Neim sat down completely.


  143. M***t

    Excellent device, worth this money, thank you


  144. R***r



  145. E***v

    Low quality measuring wires. The 300mAh battery comes down very quickly. The price seems to be overpriced. But in general, his pounds fulfill.


  146. C***v

    The goods did not come the money returned


  147. A***v

    The product corresponds to the description. Delivery about month. Package packaging is very reliable. The battery was discharged.


  148. R***r

    The device lasted almost three months. He left China for a very long time. The rest is fine


  149. C***l

    Fast shipping and very good packaging. The item is of quality. I have not received a manual but You will find demos on You Tube. Do not forget to calibrate the device!


  150. S***k

    An interesting device for an amateur radio.


  151. Y***v

    Thank you.


  152. S***o



  153. M***.

    Everything works.


  154. K***A

    Received the goods quickly, well packed in a box, checked everything works. There is no instruction that to translate paper to a specialist and so everything is clear, if there are questions I will look on the Internet. I’m happy with this store.


  155. Customer

    Recomendo o vendedor, atendimento com rapidez e qualidade.


  156. A***L

    Works perfect!
