The Band snap type strap that came with my Band has come off numerous times and I almost lost my Band. Couldn’t take it anymore, so I switched to the included regular watch type strap. That snap type strap shouldn’t even be part of the Band, it’s just too easy to come snag off.
I thought I would prefer the standard watch band type but I never installed it. I have been using the snap type that came on the band for a month and a half now, and I have had zero problems with it coming off or loose. I think I’m going to keep this one on at least until it breaks and I need to change it.
EDIT: Dec 4th & my Wyze band is still going strong. So glad I got this slim version before they changed it to the ugly fat version selling now.
Don’t worry, the band will catch on something and then it will fall off your wrist without you even knowing it. Each time mine unhooked, I didn’t feel it but luckily I saw it slipping off my wrist and caught it. I’ll never trust that type of band again.
