I bought this watch based upon it's style, the advertised features and functions and price. It has met all of my expectations and then some. The app has some nice features and it does a good job of monitoring my vitals.

Set up was very easy. It came almost fully charged. Phone app was easy to install and watch paired easily with phone. It functions as advertised. Scrolling is a bit slow at times, but it works.

This is a pretty decent Smartwatch for the money. For the price the battery last a really long time and I really enjoy wearing this device.

This smartwatch is a great upgrade for me from my previous fitness band, it is loaded with features!

First to my surprise, the language support, it comes with multiple language options. Coming from a tiny fitness band, I was worried about the size of the screen. However, I was wearing it to sleep for the past two nights and did not notice it at all!
It is rather comfortable to wear it throughput the day.

There are many features came with the watch, I can sync the health data to the H Band app. There were lots of watch faces to choose from within the apps, I can changed it depends on whatever I feel like that day!

I love the high heart rate alarm feature, which I don’t see in my fitness band. The sleep analysis helps me to see the time during the day where I sleep better and provided suggestion on how I should improve my sleep. It is an awesome watch for me, and I love it!

An HRV Lorentz plot is a charting of heart beat information that gives some indication of heart health. It's just a programmed function on existing data. It would be nice if this had that. Otherwise, I like the O2, EKG, Sleep monitor and Blood Pressure monitoring of this device.
