CNPGD Smart Watch, Fitness Tracker for Men Women, Bracelet Band with 24 Hour Body Temperature Heart Rate Monitor Blood Pressure Blood Oxygen(SpO2) Waterproof smartwatch for iPhone Android Phones(Red)

Functions nicely. App could use some work but it functions fairly nice as is. Battery lasts longer than other watches that are similar. Overall, I like this unit better than others I've tried.

This is a terrible device and is being returned.App worked ok though tedious to set up but device itself is awful.In fact this must be written by my ghost because according to this device I am dead.When comparing readings on this device to known accurate devices (I have separate BP, Pulse Ox and Temperature devices due to mild emphysema and cancer) this device is totally inaccurate.Body temp when not simply displaying "Lo" averages almost a degree low. Heart rate shows low 50's when is actually right around 70. Blood ox (SPo2) indicates 88-90 with actual being 97-98 and blood pressure is just stupid with readings like 88/50, 90/58, 68/40 etc. while actual was 130/78.I purchased this primarily to monitor the health items indicated above via a single device vs 3 and have not tried any of the other features as they are of no interest to me however, I did somehow log 56 steps sitting in my chair soooo....And before anyone asks... yes I fully charged it (a whole other story trying to get the band off for charging) and yes I had it on tightly and yes I have tried both wrists and yes I have deleted and reinstalled the app and yes I have reset the device as well as my phone. And yes to all else!Bottom line, this device is not only inaccurate and a piece of junk but is potentially dangerous regardless of the manufacturers warning that it is not to be used for medical purposes. I strongly suggest you run not walk away from buying this Item.

What I like about it is that it vibrate when your body temperature starts to hot. That's why I really got it. I had one before but the charge board got broke off in the band when I was trying to take it off to charge it.

I ordered this after my other one wouldn't hold a charge anymore. It does just what I need, heart rate, BP, temp, sleep. That's all I need it for. There are plenty of other things it can do, but they are options, not required. My other one would hold a charge for up to a week. I thought that was great, until I got this one. I am literally a few weeks in and it is still above half battery. Amazing battery life

Difficult to initially connect; keeps disconnecting & 19 out of 20 attempts to reconnect fail; reading vary wildly & usually distressingly inaccurate (tested with other devices.)... I was so excited all this functionality was in one device!I talked to tech support. It reconnected then disconnected again 24hrs later.RETURNINGAsking for a replacement. Will re-review replacement. Hopefully this one was a defective exception.The replacement is so much better, but I still have some (minor) complaints. I've only used the replacement 3 days and I want to give it a week at least.Love the performance. Especially for the price! The battery will no longer hold a charge though. I am returning. Bah. I can't find it, so can't return it. I discourage this product.
