So mainly battery issues. I can't argue, it's going to be individual issues, but it hasn't been a problem for me. I have no idea how many hours I've used it. probably not 80 charge/discharge cycles. I also don't let it run totally down before charging, when it's been on 2 beeps for 2 or 3 days (at about 100 minutes use a day) I just go ahead and charge it up again. On average I guess I charge it once a week, but I haven't ridden consistently all that time and I never came up with a good mount for my winter bike so I've probably only charged it 20 or 30 times so far.

I've got no qualms about splitting it open to replace the battery if I have to, and when I reseal it, I'll use something easier to take apart (probably silicone that can be knifed open again and a durable tape wrap (3M clear repair tape) rather than cyanoacrylate or RF welding, whatever they do).
