As an adult with a bike pump now, I feel so spoiled. As a kid riding around the neighborhood on my bike, I had one of those giant pumps and you had to fold the foot pedals up and down and pump it with 2 hands. I had no idea what a PSI was and just pumped it up until what I felt was right, which I had no idea what that meant at the time. As an adult now, and with technology, I just press a couple of buttons and let the electronics do all the work. This pump is so much more portable than pumps from the past and so much easier to use. It conveniently goes in my little gym bag and is versatile. I can pump up my basketball to the exact psi I want every time without having to guess and check. It pumps up quickly and turns off at the preset PSI that I want. This is an excellent pump to have around at an affordable price.
