Well, my first FINIS Swimsense's band had its holes start ripping apart. Now my second FINIS Swimsense weirdly reset itself in the middle of the workout. My first was over a year old and out of warranty. The second is a bit less than a year.
Thankfully I got an Amazon email saying my new Garmin Swim watch has shipped. I'm hoping that it will last longer than my Swimsenses....
