After some considerations about smart watches I finally decided to buy a Pebble this summer (some weeks before the price drop to 99$). It worked just fine and I finally got notifications for phone calls I cared about, emails, messages (thanks to Pebble and YaNC).
Everything worked until I start getting some weird behavior on my Pebble screen: random pixels, some white/black line. Changing the watch-face usually solved the issue, but it started getting worst to the extent the screen was no more readable. Getting a notification and being unable to read it was totally making my Pebble not usable. Even just reading time and date started to be odd.
