Pebble watches have a devoted following. (I used to own one, OG, before it died.)
Some things that point to the profile of a happy Pebble watch customer imo.
1. The screen is most visible in bright light outside. It's reflective.
But it is accepted that in medium to dark conditions the backlight washes out colors on the Time (TS) and Round.
2. Long battery life except for the Round (which is average).
3. Good water protection except of the Round.
4. It's OK that Pebble Time (TS) and Round have the biggest smartwatch bezel ratios.
5. Accepting that customer service is e-mail only. And CS response times can easily take a week +.
6. Pebble watches are cheaper.
7. It's OK that Pebble watches have more limited functionality compared with the Gear S2, Android Wear or the Apple Watch (no answering phone calls just using the watch paired with the phone, no NFS pay system, no assistant like Google Now).
The only thing on this list that I couldn't deal with was the week+ lag in the e-mail only customer service.
Otherwise I'd probably still be a Pebble watch owner.
