The pump does not even have survived a first use with me. Generally, it works so that both front air comes out when one winds the pump, as well as when you compress again. After about half of the inflation it worked only when compressed.
By addressed very small size I have, mainly because the front handle part is also very small, repeatedly pinched fingers. In addition, due to the short stroke travel is very tiring to pump up more balls in order.
Better use a conventional bellows!
