Does not accurately measure BP

This watch has been really nice and helpful. I wanted something that would help me track my steps and sleep because I’m trying to be more healthy. I knew that an Apple watch was way more expensive than I wanted to get. I was looking for a good watch that could do the trick for me and this was the one. I had tried previous watches in the past, but they all seemed to not function great. This one has been able to track my steps and my sleep along with other cool health features like my heart rate. 
It is really cool that you can have it so that it constantly tracking things throughout the day and night. I found that if you kept all these settings on, however, that the battery would be depleted quicker than if you did not have them always on. I like to keep the heart rate tracking off and only check it every once in a while and that seemed to extend the battery life more to what I wanted which was like 3 days or so. The nice thing is that charging it is quick and easy.

This is a really great size for wearing daily with being able to see my notifications without having to look at my phone.Great vibrant colors on the screen and the options for turning on and off notifications you want to see.It is easy and I can track my steps and calories on a daily basis & weekly.To start it needs a mobile app that is easy to download/setup via QR code.The battery lasts for days without a recharge, which takes a very short time anyway.Well worth the price.

What I like with this product? Well first of all the battery it is so much better than the previous smart watch I have.Battery last long than expected. Bluetooth device works great and pick up signal more than usual.Tells my daily activities accurately not to mention all physical activities .I don't have to worry it tells me exactly how my heart is doing.Very easy to use smartwatch no complication at all and very affordable

I've had this smart watch for about 2 days now. I knew purchasing this watch that is was not a Samsung Watch or an iWatch- if you are expecting that level of functionality then you'll need to spend the $300+... So for the price, I had reasonable expectations.It's pretty sharp looking just as something that tells time and date (syncs off of your phone) and the turn wrist to see display is pretty darn useful and can be tailored with regards to sensitivity and how long the screen stays on.I had no issues pairing the watch to the app (you should pair the watch through the app, not directly through your phones bluetooth function).The app itself is basic but easy enough to maneuver through and gives more info on the health functions of the watch. I have not compared the BP and SP02 results against calibrated instruments, but feel the results are fine as a ballpark reading for use in workout and sports (readings needed for medical diagnosis should probably be left to the realm of calibrated instruments).The watch does vibrate whenever I get a text or email (that function can be turned on/off).Ultimately I feel it was a good purchase- battery life has been holding up fine and the app hasn't been affecting my phone much that I can tell (Samsung S20 FE)...

Very well made. Easy to place and remove bands. Touch screen works very well. Box comes with 2d barcode printed on it to help find the app easily. So far the info that it keeps track of is pretty accurate
