I just ordered one that should be delivered sometime this week. It is my first, so I have no actual experience with them yet to report to you.
I DO have a FitBit fitness tracker, but it has been spotty on reliability and very inconsistent in accurately counting steps in recent months. When I saw that Apple released the SE watch series that sounded like a bargain price for the features it provides (as compared to the most recent series 6 watch) I decided to save up my Amazon credits and finally bought it for $0 out of pocket when I had enough credits.
