Query: Works great, but has some drawbacks

Let me start first by saying the positive aspects of this item.This pump does work and it works well. Its gauge has a knob that you turn so that once it reaches a certain psi, it turns off automatically. This is great because you don't have to stand around watching it to make sure it doesn't over-pressurize whatever you're pumping. The gauge is also illuminated for nighttime use.Now for the drawbacks. Unless you're pumping up a bike tire or something small, this pump takes a long time to pressurize. Also, the wall outlet cord that comes with this pump is ridiculously short, around a foot and a half long or so. Also, the tube you hook up to whatever you're pumping is really short too, probably around as long as the cord.Overall, however, this pump is great for its price and I'd recommend it if you have an extension cord and no need to pump something up quickly.
