    I liked the bracelet, neatly made, there are no instructions on Russian, I had to look on the internet how to configure it, it turned out. I checked the readings on the measurement of pressure and pulse with a tonometer, there are discrepancies, but not significant.

    The watch ordered on Ali 13.11.19, waited a long time, which was no longer hoped. But everything is fine, the clock came on 26.12.19. The parcel was received in the mail. Packed in a special film, and the watch itself in the box were that in fact does not threaten their deformation during transportation. I waited for them very much, because I really wanted such a watch. As they came and what was, see the photo below. The quality of the strap is very pleasant to the body and to the touch. The watch is very beautiful and bright. Instruction in different languages, but alas neither Russian nor Ukrainian. Tried to connect them through the code, but alas. I decided the question simply, went to The Pley market and downloaded the program manually. Everything is set up automatically, date, time, etc. I still understand them further, but I like the clock very much and I’m delighted with them so far. A little later I will sign for the quality of use) I recommend the store. Thank you very much! P.S. My expectations were worth it

  21. M***k

    Received a couple of days ago, we still can not understand whether a good bracelet or not. in the main took for pressure measurement. but sometimes shows correctly, sometimes not. perhaps you need to choose the right position for measurement. otherwise it looks solid. maybe we’re unknowns.

    In general, a good bracelet for this money. Until they figured out how to use it, everything is very difficult. Downloaded the app, connecked with the phone immediately, but then turned off. Let’s get this straight. The store sent very quickly, the same day as ordered. The parcel was three weeks before Vladimir.

    Cool chashi. The charge lasts for a week. The strap is soft rubber does not smell. Nuran is bright. Pulse and steps measure norms. The pressure is overrun by 20-15mm. Delivery 1 month. I recommend the product…

    Ātra piegāde aproce pair to naudu going ok. Pulsu a spiedienu mēra diezgan precīzi, ķļūda salīdzinot ar profesionālu tonometru 2 līdz5 vienības. ar telefonu sasaistījās bez problēmām.

  53. V***n

    In Armavir came very quickly on January 2 ordered, and already on January 23 received. The View and touch is very high quality and pleasant. I did not communicate with the store. With all the functions included, the charge lasts for a maximum of three full days. In the photo visually it seemed to me wider than it really is. In the photo, the side frames are almost invisible, but not so, they are about 4mm wide. Still the photo shows the map. It is just for beauty, no card device displays and does not support. Moisture protection checked in the hot bath. Not sweating, everything works. I liked the accuracy of pressure measurement-the error is small (compared with the tonometer). Weak place-magnetic charging. If it fails (the cable is very thin), then the other one is not found.

    Guys, the thing is cool!!! Beautiful design, nice to touch silicone strap, pressure and heart rate accurate, there is a pedometer, calorie counter, sleep monitoring. Pulse and pressure can be measured in forced mode, or can automatically. The app in the phone also liked it. Full binding: various settings allow you to display calls, messages, SMS .. Vibration alerts. Very satisfied.

    Excellent fitness bracelet. Home photo does not convey its beauty in reality. Looks like in the picture. Pressure shows exactly. Pulse too. The only negative is long delivery. But it’s worth it. 5 +.

    Bright screen, many functions, the charge holds well. I can not sleep in it, it hinders, so I can not evaluate the work of the alarm clock and sleep counter. Steps, I think, greatly exaggerate. The pressure looks like the truth, but I didn’t check with a normal tonometer. It was a month in Moscow.

    Everything was fine until the bracelet after 30 min. The work suddenly did not buggy and ceased to clearly display what is happening on the monitor. Sold for a long time pretended to be a hose, like mine do not understand, wet the water hand is not on… This is despite the fact that the bracelet is declared IP68! Had to act formally, through an official dispute. The goods returned, the money received back. Sorry only for the lost time. There was a gift-became a headache 🙂

    Sent quickly. The bracelet came with a noticeable scratch on the screen under the glass. Opened a dispute for the return of part of the cost. The store on the dispute did not react at all, the term passed, part of the money was returned. The bracelet itself is not bad-quite correctly considers the steps, distance and pulse. Pressure measures ABS as, from Balda. It will not replace the tonometer. The app is normal, the Russian language is. A constant connection is not required-the day departed, in the evening connected, all the data dropped-it is convenient to watch and analyze. The battery holds 5-10 days, depending on the activity and use modes.

  89. A***a

    The bracelet is beautiful. Tested the day: the number of steps does not exceed significantly, the measurement of pressure error to 10%, the pulse is quite accurate, note this is not a medical device. When a call shows the name of the caller by pressing the button you can remove the sound of the call. Phone search works. From the bad-periodically turns off the application, even when the phone is nearby, if after that there are problems with pairing helps to reboot the phone. In general, I’m happy. In Kiev the parcel was 16 days.
