Review on Effortlessly Inflate Any Inflatable Item With WEY&FLY High Output Double Quick Air Pump (8108) by Solomon Inks

This pump is awesome. I had been (trying) to blow up the inflatable rings on 2 Intex pools, one 12-foot and the other 10-foot, and it was taking me 20 minutes each using the goofy foot-pump that came with an old exercise ball. This pump puts out a LOT of air on each stroke and also puts out the air on BOTH the up AND down stroke. I filled those pool rings in under 2 minutes each. Note the "large" size adapter fit the inlet port of the Intex pool perfectly.Plus, with every inflation you do, you get a free upper-body workout. Switch arms after each minute of pumping so you work both sides of your body equally.
