  2. 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.

    A***l –

  3. 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.

    A***v –

  6. 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.

  7. 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!

  27. 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!

    A***n –

  28. 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

  31. 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.

  32. S***r –

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

    S***r –

  33. 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.

  38. V***v –

    ok.

  39. 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.

    K***v –

  40. 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!

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

    A***v –

  45. 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.

  49. 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.

    T***k –

  50. 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.

    V***v –

  51. I***h –

    all ok

  53. 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.

    A***v –

  54. 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.

    I***v –

  55. Customer –

    Cool tester, I like

    Customer –

  56. 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.

  57. B***n –

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

  58. 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.

  109. 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.

  110. 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.

    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.

  146. 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.

    V***v –

  147. A***H –

    Great thing. Everything works. Came quickly.

    A***H –

  148. 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.

    Delivered to Moscow for 3 weeks. Everything works. The remotes determine not everything, out of the 4 checked issued codes for only one. Excellent purchase for this money.
