It's pretty cheap compared to apple or whoop. The sleep tracking is very good for the low price. Apple products tend to be a bit more accurate. But it does a great job and fits into my budget as a student. Measuring heart rate works also well.

The wrist band leaves some red marks if you make it too tight. I was not sure if it would provide good measurements if I loosen it a little, but it still seems to do well. Now it can move around a little on my wrist, which is annoying sometimes.

I wanted to get my sleep score and see how much REM&Deep sleep I got during the night. This should help me to improve my sleep quality.
