Review on 💦 Aqua Double Quick: Advanced Heavy Duty Air Pump for Inflatables, Air Mattresses, and Sports Balls - Dual-Action Hand Pump with 4 Nozzle Attachments, Black by Brian Campbell

I bought 2 of these pumps. Unfortunately, I threw away the packaging before testing or using these devices, so I cannot return them. One block didn't work at all, and the second worked so badly that it was mostly unusable. All these types of pumps are so simple that I thought I could solve every problem. Each of these pumps has two simple air valves attached to a piston. The piston creates a seal along the length of the cylinder to create the air pressure needed to get air where you need it. The problem with these pumps is that they have a very imperfect barrel design. The molded plastic is so fragile and thin that the barrel can be folded with just two fingers. The piston will never seal the entire length of the barrel unless you make a new barrel. I just can't fix bad design or bad production. To mark
