Fitness Tracker with 24/7 Heart Rate Blood Oxygen Sleep Monitor,Activity Tracker with 1.1" AMOLED Touch Color Screen, Multiple Sport Modes Step Counter,IP68 Waterproof for Women Men (Dark Black)

My sister loves this. She wears it on her ankle cause she doesn't have enough meat on her arms for it to fit. It works great for her.

Sometimes it takes several minutes to pair with my phone. I'm not convinced the blood pressure is accurate because it's all over the place. I wore it for a hike and had it on sport tracking for the hike; it kept randomly pausing the workout to where I had to manually unpause it multiple times, resulting in a completely inaccurate record of the hike. Despite setting it to where only a touch turns on the screen, it keeps turning on when I move my wrist, so I just take it off for sleep. The app is easy enough to use but the watch sometimes resists pairing, which is annoying. The sleep tracker isn't entirely accurate, I've definitely woken up a couple times and it had no idea I had been awake, and on more than one occasion claimed I got no REM sleep despite sleeping over 8 hours. The find your phone feature doesn't work for me. It's just wonky and I think it BSes a lot. You get what you pay for.

Before I give the reason why I gave a one star review. I will discuss the biggest reason why I returned this monitor. I am actually the type of person that values privacy and I actually read this company’s Privacy Policy (as painful as it was) at 79 pages long. You can all thank me later. So if you download the Chinese App It clearly states in Privacy if you decide to connect via Bluetooth, cellular, Notifications, Location Tracking etc. It will automatically send all your data back to an Internet technology company in Beijing China. Why? You can only imagine. I tried to limit my exposure through their account settings and just use it for heart rate monitor and blood pressure when working out. However, the app is then useless because it won’t transmit from Phone to device and the functionality becomes very limited. Lastly, the accuracy is way off. My old heart rate monitor always had my rate at 142 bpm when I am sprinting on my machine. This monitor has me at 96 -101 bpm. Impossible! I tried this a few times and found the same result. Moreover it refuses to constantly monitor any one function. It’s designed to bounce and give you snap shots of heath data. Not useful while working out and monitoring vitals.

The display is clear. However the blood pressure reader is 30 points off according to an actual device from the doctor. The other issue I have is in the water every time my arm goes under the water it triggers the touch sensor and changes the screen so I can not use the stop watch or anything when in the water. The steps are not accurate in the slightest and sadly doesn't count if you have to push things around or carry them. The notifications work well. The size is average for something like this a bit restrictive for my wrist though and the durability is fairly good so far no scratches.

The watch itself is not that bad, for the price the watch is sleek, nice screen and monitors a lot of different things which is nice. However it only operates and sends information to one app and that app is completely useless. I downloaded it and tried to set it up with my watch and it just kept crashing. As far as I have read and seen though it can not link up to other tracking which means you would have to manually enter it into your fitness apps.

While I find this to be accurate while you are not active, it doesn't work when I go on a bike ride. At all. I thought about returning it but it seems like most fitness trackers have this problem. I ordered a chest strap instead. I will still use this for sleep tracking which I believe it to be reasonably accurate. Not sure about the REM sleep accuracy, but the deep and light sleep appear to be accurate enough. I would return it, but unless I spend a lot more money, I believe I will have the same problem. All that said, the "fitness" part of the item description is misleading.

It is not touchscreen. The fitness tracker also doesn’t communicate properly with the app and does not record workouts accurately. I bought 2 of them for me and my partner and neither are accurate. The screen image is good quality but is on a different screen every time I raise my wrist and I have to go through all of the options before getting back to the Home Screen. I’ll be returning both.

Great in theory but very innacurate. If I start a workout on the watch, it says my heartbeat is a constant 97 bpm no matter what, if I exit the workout and have it measure, it will say 125, 150 etc depending on how intense I'm going. The sleep tracking is laughable, says I slept straight through to 8am! I got my kids up for school at 6 as well as at least 2 other wake ups. I gave it a few nights to see if it would get better, tried adjusting the tightness etc, its all still wildly innaccurate. The only good thing I like about it is that it sends my notifications from my phone, as I don't always carry it in my pocket while at home. I'm going to be returning it unfortunately.
