I cant be certain of course, but what you wrote in the opening post did surprise me. I mean, I use it at least once a week, and it is pretty fast and hassle free to me. I'm not saying it is the best floor pump in the world, but it does a decent job. Something seems off. But hey, if it does not work for you for wahtever reason, then get something that does. I also prefer pumps that you can screw on, though I also like how fast you can attach and detach with this kind of system.
