I recently purchased your MagiAir inflator/deflator Model 1-IDAR for use in my cigarette Iighter. I had just bought an inflatable queen size air mattress to use when we go camping, and normally, the stores displayed this with various makes of 12 volt inflators. Much to my dismay, using one of these products meant preparing well in advance for your trip, because apparently it was going to take two days to blow up the mattress. As I was planning to head for Colorado shortly, and knew that we passed the Cabelas store in Kansas City, I checked the Cabelas catalog, and saw your product displayed. We went to Kansas City, bought the last one on the shelf, and headed for our camp. That is why am writing-not only is your product made in US (very important to me), it is well made, easy-to-use, and does exactly what it promises in an amazingly short time. It took under 10 minutes to fully inflate the mattress, and about 30 seconds every couple of days to maintain it. Then it helped on the way back by deflating it quickly and thoroughly. Thank you for a very satisfied customer for making such an excellent product.
