Familiarity: I've used it several times
I go backpacking a lot with my wife and we have two large size (25x77) neo air pads. This thing is great. It takes about 3 minutes to inflate each pad to about 90 percent. So far I got about 10 inflates out of my set of rechargeables (eneloops) and it is still going strong.
Works great though you can get by without it. I think the pad might last longer with it, since you are not blowing moisture into it.
One thing that I wish I could do is reverse the flow and deflate the pad. I don't think that would with current generation of Thermo-a-rest. Actually, it would be even better if Neo Air had a deflate valve, like most of Exped pads.
