This is a neat idea. It works so well I bought 2 more for my family. We've been using 3 of them since 2008/2009 while backpacking.
It works great as both a pillow and as a way to inflate an insulated air mattress pad without getting breathy water vapor moisture inside your air mattress/pad. (who needs mold growing inside the insulation of your air pad?!)
It takes me about 3 minutes to fill a Big Agnes Dual Air Core Insulated (wide/long) pad. It also works with my Pacific Outdoor Equipment "Ether Elite" air mattresses. (both require one to use the included 1" long silicone adaptor hose to reduce the diameter of the fill hose). Both the POE and BA air pads use the same size valves. Both pads have insulation in them which could potentially retain water vapor, so using this air pillow pump to fill your air pads with "dry" air is a good idea.
FYI, using this pump does require a special technique or finesse which was discovered by my son.
One must use the palm of your hand to cover and seal the fill hole. Your palm can make a really good seal. If you try to use your palm to press and hold the plastic fill cap in place over the fill hole, air seems to leak out around the fill hole and the hard plastic cap during the filling process. So just flip the cap out of the way and use your palm directly on the fill hole. Then compress the pillow (like you're doing slow motion CPR) to fill your pad.
There also appears to be a one-way valve built into the fill tube, so if you've got a good seal at the fill tube/adaptor valve, then no air (or very little) leaks out or backward into the pillow during filling. Nifty!
It also makes a great pillow. I like the contoured shape. It probably could be lighter or easier to use, but I like it. The only thing that I don't like is sometimes when compressing the pillow during inflation of an air mattress, the 1 piece foam inside the pillow squishes or rolls out-of-shape. But one can massage the pillow foam back into place easily.
This pillow pump did come with stuff sack and repair kit.
