I bought this to quickly inflate my bike tires before a ride. It does its job very well and I'm very glad I bought it. Nice: > Between the cable and the spiral air hose, this pump can be used at a reasonable distance from the car. I didn't want to maneuver the bike to get in position for the task. I can easily inflate tires to this distance if it is mounted on the back of my Subaru Outback and the pump is connected to the dashboard. > The rate at which it inflates is decent and manageable. I was worried it would inflate too quickly and I might inflate again. The speed appears to be around 1 pound per second.> The gauge is easy to read and accurate. There is a number for every 20 pounds, a big tick at 10 and a small tick at 2. Meh:> It's a bit louder than I expected but not too bad. The noise is audible but not bothersome unless you're trying to pump air at 4am with a sleeping baby nearby. > It has a 12 volt plug that interferes with trying to inflate or use the air mattress. in your home. Eeek:> The case it comes in is flimsy and of terrible quality. It actually broke due to the pump's own weight bouncing around during transport. The pump sits loosely in the housing and thus offers minimal protection.
