There's a review of it, I heard that it's quite hard to get one though with some best buys only getting 1-3 pebbles and some getting none. An article said that it may have been a marketing strat.. but you never know lol
Here's an article on their sales

All in all from what I've read it seems like a really nice accessory for any smartphone.
Though I think Apple might be making a smart watch as well, and as of now the pebble is pretty limited.. but I guess it depends on what you want.
