that is , so far, indestructible and have worn it for years.. i went through two Fitbits, but their downfall was in that they were not waterproof, so had to take them off for every shower, dive, pool day etc.. Where their design was flawed (and this may no longer be an issue) was in taking them off t least once a day, the area where the band connected to the unit eventually wore out.. and that particular area was sensitive toward the Fitbit's operation.. once that bond broke, the Fitbit stopped working.. I went through two of them that broke the exact same way..
So, the $25 Garmin I got is waterproof, so never have to take it off.. its maybe 1/2" to 3/4 wide, so do even realize I'm wearing it most of the time.. have replaced the battery in it 4x and it just keeps on working..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
