Probably received free replacements. I had 3 break down on me and only once did I have to pay shipping, coincidentally that was the last time I asked for a replacement. perhaps I am bitter.

Their support was great but when it doesn't perform the basic function of syncing with my phone or desktop app, what good is it? I had software and hardware problems (band breaks easily) on all of them.

Yeah, they were good about giving me free replacements whenever I had an issue, if not I definitely wouldn't have purchased a new device. I just swapped in the new replacement screen this morning, hopefully it works for a good long while

How's your battery life at this stage? Have you replaced the battery yet?

I just upgraded from Series 0 to Series 5. Passed it down to another family member. Battery still lasts whole day, and in general it was doing same tasks as a new one. Biggest issue I had with the old one is that it wasn't waterproof.
