Yeah that shits a scam. My girlfriend bought one less than a year ago for her XR and the frame just popped out. It was supposed to have some shock absorbing thing but it’s unusable. My Apple silicon MagSafe case for my 12 Pro is poor quality but ultimately lasted longer (since the launch of that phone)
I use it for those purposes and it’s fine. I do think the Apple Watch has become a lot less useful overtime since launch. I would recommend getting something a bit more accurate with longer battery like a Garmin
