Seems like a neat concept. The device uses a tire to keep the unit inflated, so no need for pumping or for a large air compressor. Adapter caps look decent as well.
However, the air inside of a tire isn't exactly dry....so it may be worthwhile to invest in a $40 portable air tank. And I would fill the portable air tank with Nitrofill from the free inflators in the Costco parking lot.
