I had my pebble watch a few weeks ago and actively using it. In general watch is really good. However it has some issues. Some pebble owners face oily looking screen but I was lucky to get working one. Battery life is 5 days in average, changing 4 to 7 days with usage. Most of the iOS notifications appear on watch except whatsapp (most important app for me) and watch doesn’t use unicode encoding. Caller ID is a really big problem, already memorised most popular phone numbers in my address book, thanks to Pebble !!!
