Just finished 4 nights with one in Canyonlands.
Noise just isn't an issue. It's more comfortable than my IAC. It feels more stable, and I appreciate that it is rectangular rather than mummy shaped. My gut feeling is that it is at least as warm as the IAC.
My problem, though, is that it won't stay inflated! I'm a bit disappointed, to say the least. I haven't given it the bathtub test yet, so we'll see in the next day or so. It takes half the night, but I end up having to add another 2 or 3 puffs to get my rear end back up off of the ground. I've tried starting with the thing fully inflated, but still ended up aground.
I though perhaps at first that the change in inflation could be due to air temp, but I'm no longer convinced. I picked the thing up in Friday evening, literally threw it in my pack, and was using it Monday night in Salt Creek, so I just didn't have time to mess it up on my own.
My future review will include info on the comfort and warmth as well as CD customer service. :(
