KrazyKid: Mine lasted until it went through the washing machine.
Grrr. Still regret not checking the pockets.
Bah hah hah at least my pebble is waterproof.
I'd agree with other speculators and say 2 years. I've had my pebble for over a year now. It's fantastic and they are good value. I do however want the round one but I'll hold of till next Christmas which will make my current one 2 years old.
