I know 3 people with pebbles. All 3 have had the screens stop updating properly after several months. Plenty of other folks on the forums also have display problems. I feel like it was an ok level of satisfaction for a kickstarter and proof-of-concept, but nowhere near good enough for me to stick with the platform. I'm just hoping it inspires another company to do a great job of making an awesome e-ink watch now that the market has been demonstrated.
