I don't care what anyone might say, I wish I hadn't bought my Sigg water bottle. These things taste nasty after not too long of time. Sad thing is this was to replace my BPA riddled Nalgene bottle. I've had Klean Kanteens for quite some time now, and so far, I've got nothing but good to say about KK. If you're in the market for a new water bottle, save your pennies and stay away from Siggs. Unless you enjoy highly dent-able bottles that make you water taste nasty.
