I've had 2 Tickr Fits, and I've had several fits over my Tickr Fits. Both examples (bought one, got the 2nd as a warranty replacement) sometimes turn themselves off and back on. I use Bluetooth, though; maybe they're better on ANT+. My 'piter doesn't do Ant+. I really liked the OH1 I had, but the battery charge lasted only for a ride and a half. My next one may be a Scosche, but I'm afraid that has problems, too.
