This is a great mini hand pump for those simple inflation jobs such as Beach Balls between mini 4-Inches to even larger 16-inch and larger if you have the endurance. Smaller beach balls inflate with a half dozen or so pumps and great when electric or larger Hand Pumps are not needed. BEACH BALLS ARE MEASURED DEFLATED END TO END.
This is a manual pump that may take some getting use to as they all do. Once you have the technique down, it's a breeze plus a little exercise.
