it took me a minute to figure out how to use it. you attach to your car tire %26 it will read the current pressure. you can then set it to the pressure you want it at %26 you click "the trigger" %26 off it goes. Filled all 4 tires %26 the rechargeable battery is still full. finally, the warning light on my dash turned off!

Good Tool

Pump works fast, much faster than my old one did when it was new. Comes with everything you need. Just put the battery on it and you're ready to go. Advise fully charging battery first. It reads full when you test it out of the box but it's just a surface charge.

Quite impressed

Shipping was super fast - arrived next day. I'm quite impressed with it so far. Very simple to use - just push the plus sign until you reach the pressure you want the tire filled to, attach hose to tire, and push start. It will stop automatically. I put roughly 10-13lbs into each tire and it took about 3-5 minutes per tire. The battery did die after the third tire, but honestly, I wasn't expecting it to last that long. A few minutes on the charger and finished the last tire.
