i picked this up from the store, which was super convenient, and i've been using it for a couple of weeks now. it's like having a little health coach on my finger—very helpful for tracking my sleep and stress, especially after concerts when i'm exhausted. the build is sleek and durable, so it holds up well with my active lifestyle. i'm married, and my husband even commented on how it blends in with my style. overall, it's a great tool for staying on top of my wellness without any hassle :)
- Pros: i love how light it is, i barely notice it on my finger, and the sleep tracking is very detailed—it tells me about my deep sleep and when i wake up, which helps a lot. the stress and recovery insights are a beast, guiding me on when to rest or push harder, and for women's health, it makes sense of the data without being overwhelming. plus, no extra fees to use it, which is awesome, and being able to use my health savings for it was a nice bonus.
- Cons: sometimes it feels a bit pricey upfront, and the reminders to chill can be a bit frequent, but that's minor. as it seemed to me, the initial setup took a little time to get used to, but nothing major.
