I was very excited to receive my Pebble Time bumpers. I tried both the black and the metallic one and decided that for now I preferred the Black Strong & Flexible one.
Wore it all day no problem. Kept it on during the night only to find that it had come off in my sleep. No big deal, I just clipped it back on and went on my merry way.
Wore it all day at work, showed it off to my coworkers, came home and ... oh no ... it's gone! I've lost it. My black bumper and I shared a mere 24 hours together only to be separated again.
I think the idea is awesome and I was really excited when I found. Needless to say, I'm less excited about it having come off and gotten lost after the first 24 hours of wearing.
I strongly recommend you revisit your design, because this one needs some serious perfecting.
Yours not so truly,
