All the positive reviews are correct., March 1, 2010

So, I bought this having read almost all of the reviews on here: they are correct when they say this thing rocks! I had a low tire--a 235/75 R 15 truck/SUV at about 25 psi--on a very cold day: about 5 F out. Plugged it into the 12V jack in the SUV and connected the screw-on nozzle and let it do it's thing. It was pretty quiet and filled the tire to 40 psi in 4 minutes and 2 seconds. Not bad considering the cold weather and this SUV weighs about 5000 lbs! And, this thing is small enough to store in the vehicle without taking up too much space. AND, the extension cord was really long to go all the way around the vehicle. Well worth the $40 bucks!
