When I got home and saw my box it wasn't crushed or there was no mark on the box but when I opened it my 11- Pound wire 0.25 was on top regulator I pulled it out and saw the tank gauge was broken like they had thrown a wire over the top of the regulator. I think it would be a good product but they broke it before I could use or test it. They had to refund me my Revain gift card money but who knows we'll see if they can do it. .
