My apprehensions were unfounded
Customer Rating: 




Having read the reviews critical of the chuck, I was a bit apprehensive about this unit. At this point I had spent about $400 on various compressors and tire inflators; my way-cool Craftsman rechargeable inflator has a clumsy chuck that loses its hold on the valve stem (and which stopped working after its valve-opening pin broke), so I had to use my larger compressor to inflate some tires for an autocross recently. But the chuck that came with that set-up was totally useless.
Which brings us to the C-H inflator.
I managed to turn the gauge so it's situated athwartships, plumbed on a quick connector, and fired up the compressor. Zip! The chuck slipped onto the first valve and stayed locked in place with no hissing air leaks! A few pulls on the trigger, and the gauge read 40 pounds. My Longacre gauge read 38 psi, which is just fine, since that's what I wanted. So zip, zip, zip, the rest of the tires were
brought up to "C-H 40" and I was good to go.
For thirty bucks (on sale for some reason) and free shipping, I'm more than satisfied.
