I bought this pump in conjunction with a Coleman Comfort Control Air Mattress and I'm very pleased with both.  The pump filled the air mattress firmly in under a minute when plugged in, and the pump seems to hold a charge quite well.  The nozzles included make the pump ideal when inflating a Coleman air mattress, as they're custom made for each other.  The air pump takes the next step, though, in including additional nozzles that would (presumably) enable one to easily fill other inflatable items (short of a basketball or bike tire).  The only minor annoyance to me was that the pump is quite noisy.  If you're planning to use this at the campground, try to make sure you get your business done before other campers go to bed, especially if you're in close proximity.  (Also, this product would have been pretty close to perfect if it had 9V car adapter capability.)  Outside of that, this is a very efficient air pump - the price is more than worth the assurance that I won't have to spend an hour laid out on the tent floor getting chapped lips from blowing up the air mattress.
