Absolute crap! When reassembling, apply Teflon tape to all connections to prevent leaks. Wanted to use it and the air didn't go through the gun. The deflation button worked great to remove air from the tire it was attached to, but didn't fill the air. I thought it was a bad pad so I ordered a second one. The second was also garbage and the trigger does not work. Return both blocks. FYI, batteries are required so plan ahead. The package has a slot for batteries but they weren't. The only reason for two stars is that the device looks like the picture and arrived on time.
