Huangchao Inc Fitness Tracker, Smart Watch 4 Sports Mode, Heart Rate Monitor IP67 Waterproof Activity Tracker, Sleep & Blood Pressure Monitor, Calorie/Step Counter Smart Wristband for iOS Android

I bought this for 2 reasonsIP68 and for the blood pressure measuring.While the description clearly states IP68, the manual says IP67.... I swim around in pools all day as a leak detector so this was crucial.2 weeks in and I'm guessing that it's indeed IP68.... though I really haven't swam more than 8 feet down with it so far.The blood pressure readings DON'T transfer to the app and there's no way to manually input it into the app which is a huge bummer.... this is the main beef with the watch, per other reviews.The battery life is really good, though that's no way to gauge it. I just throw it onthe charger for ten minutes a day and it's fine.It's comfortable, I forget that I'm wearing it.The heart rate monitor is always close to what my GS9 says. My blood pressure reading is always 20 points off of what my cuff reads so I need to see which one is accurate.Besides the face scratching way too easy and not being able to track the blood pressure, it's so far a good purchase.

It seems that the accuracy of the device is not that great. Perhaps, the measuring algorithm needs to be adjusted. Couple of noticed issues: when I am running on a treadmill for about an hour (4 mph, 14 degrees incline), obviously, my heart rate can't be 70-80 bpm, but it shows that. At the time, the heart rate was set to "continuous measurement", so it's not an average for a long time. Then, when I took the bracelet off my hand and placed it on a table, and then pressed "measure" on the app, it was still measuring and showing numbers! Uhhh, what was it measuring? Also, when the bracelet is off hand and laying around somewhere, and if it's past 11 pm, it will take it as "deep sleep" period, which also does not make sense. However, it kind of shows the patterns of high and low bpms throughout the day. So, the trends are right. But, it looks like it's 10-70 bpms off. Good idea overall, still needs tune-ups.Few suggestions:Improve recognition of the sleep. If the motion sensor is not showing anything and bpm is zero, it means that it's not being worn.Add a capability of downloading the bpm (and other) patterns to a computer.Add a capability of logging the blood pressure readings on a chart.In the manual, add some suggestions regarding calibration and improving accuracy of the device.Make the charger port a little more robust...

I chose this one , because Blood Pressure Heart Rate Monitor.Before that i used ear phone with Heart Rate Monitor.But since my runing place change to the park have a lot wild animal. I dont want to wear earphone .Been test few day with two important Features.Heart Rate working fine. cmy earphone some time stop detect. this one didnt have that problem.Blood Pressure are fine to. Just dont compare to Medical blood pressure Medical blood pressure .But since i move a lot, dont want to bring my Medical blood pressure monitor. This small watch help me monitor.NOTE:But be avoided If you have hight blood pressure need medical treatment.Use your Medical blood pressure monitor frequently.

The device was received in a nice box (I wasn't expecting it) The setup was a little tricky. I had a hard time connecting it to my cell via Bluetooth.... (I have an LG G6 Phone) After a few resets of the phone it finally worked. In the mean time I contacted the vendor who immediately replied with suggestions. After a month of use I have tested all of the features of this watch:1- Awesome battery: Over 10 days with a simple charge2-Blood pressure: High accuracy compared with a commercial blood pressure device3-Water resistant. I have used it while showering everiday and even while swimming on my pool..... with no signs of internal water damage.4-Printed documentation could be better5-Receives text messages from my Android phone6-Vibrates when receiving a phone call7-Walk steps not very accurate.... but close enough.7-Most of the functions require to have a phone connected via Bluetooth (sleep monitoring, blood pressure, hearth rate, etc)8-Vendor is very motivated to provide an excellent customer service.

I love the looks and size of this watch, but it gets lost . . . . I bought it mainly to keep track of my steps and my Blood Preasure, I don't need the swimming and running training, so I don't mess with it, but once in a while when I look at my watch it is in the swimming or running training and I can't get out of it. I follow the directions on what to do to get to each function, but it is a hit and miss. It is not very steady.

I used it at the pool and it worked. Most importantly for my purposes, the blood pressure measurements are inaccurate. I tried it a few times to compare a stationary device, which is reasonably accurate, and it was about 10-12 mmHg off.It doesn't pair with my Android S7 phone , and without that there seems no way to set the clock. The display keeps resetting itself to the clock, and every time you go to another mode, you need to go through the menu.Returning.

I bought it for tracking my blood pressure while traveling. I have used it for a few days and had no problem at all with this watch. Also nice is the sleep monitor, steps, calories burned, etc. I've tested the waterproof feature in the pool it works great. It also syncs to my phone really fast.Easy to use, affordable and convenient. I’m am truly satisfied with what I got so far. Very satisfied with my purchased!UPDATE:I think I need to update my review because It can not be charged after I used it for a few times. I do not know if its battery dead or something else. Right now it is useless and collecting dust. I have to look for another one.
