yeah, don't think the no-dent thing will stand... I ordered a backpacker version and it came with multiple dents and the shipping box did not have anything that indicated the box was mishandle. Returned it and order another backpacker and same thing... a dent on the bottle without any apparent trauma to the box. Got it third one on order and hope it doesn't come with a dent. Have the standard version and it came without a dent. However, poured left over coke from those 2L bottles in and screw the cap with o ring to prevent CO2 lost... went to get it later from the fridge and the coke's CO2 pressure was enough to pop the originally concave bottom out... you can press on the bottom to pop it back, but still, don't think anything that'll pop that easily can be very dent-proof.

Given normal use you shouldn't have any problems with denting. With that said any stainless bottle if dropped from high enough or thrown hard enough when full of water will most likely show some kind of damage or dent (unless its made of titanium!). Keep in mind that Backcountry has a 100% satisfaction guarantee so if you had any problems with the bottle we've got you covered.
