This bottle was recertified a couple years before I received it, but it came freshly painted and looking brand new. It is a DOT approved bottle anybody that buys this should not have any problem with it.

Local welding store exchanged it for a filled one, served it purpose.

These were way overpriced locally, so I figured I’d give it a try and order one through here. Build quality is up to par and I saved some bucks, so win/win.
