I have the bigxtop handlebar bike, took it touring last summer and was great. Properly waterproof, spacious (especially if you have extra stuff to take temporarily: can leave top open) and easy to attach to bars.
Gripes:
-hard to close the catch with one hand (sometimes frustrating when trying to snack out of the bag on the move)
-clear top pocket could be pushed too far towards the front of the bike to be easily seen if the bag was over-full
-bag sometimes would shake a little in its mount
