Re: +1 for a Pebble here!
Quality Control is a little hit & miss. My first Pebble lasted 3 months, before failing to charge properly.
Mine does that occasionally, it turned out in my case to be that the charger connector wasn't making a good connection with the phone, possibly due to grease on the contacts. Provided I make sure it really is charging then it's OK.
I've had mine almost a year now, it was a gift last December. Once I finally got around to upgrading my phone from an old HTC Wildfire S, the watch got to be far more useful.
