Got mine today and I'm really impressed with the quality. The chuck, fittings and gage housing are made of brass and the gage has glass on the from and brass rivets holding thr face on. The gage says its made in USA but the box says china, maybe just the gage is made in usa and the rest in china. Has a sticker that says is accurate ti ANSI and California regulations. And it comes with a life time warranty, you just have to ship it to them with $2.50 for return postage.
