I really like them, I pretty much just mine as a fitness/sleep tracker. It is capable of much more than what I do with it I know. I am on my second one, my old first generation one still worked, but it was just so old it seemed that I was missing out on some desired features (like sleep tracking). I ended up getting a newer SE. I have been very happy with it, it does everything I want. I was also thrilled that my first generation bands fit the newer watch too. (I have this thing about bands, I have like a Rubbermaid container full of them, and I always match the band to my outfit). It takes maybe 5 seconds to change those out. I know there are some pretty high end Apple Watches out there, but the SE suits my needs perfectly.
