    • good experience
pretty neat I can order a 120 gal propane tank and have it delivered to my house. The delivery guys where great and put the tank on the other side of the house where I built a pad with a hand truck. Price was much better than the local tank suppliers at least 300-400 dollars. I had purchased a gas fireplace so the gas line was run from tank (15 ) feet to fireplace, then propane delivered. Propane delivery guy needed to check things out since first delivery so he put some propane in tank and checked for leaks on tank and in house. No leaks, everything good and filled tank.

Tank was received from the shipper I damaged with the exception of slight marks in the paint coating. Fine all other respects. Tank appears well built to ASME specs. Good value for price paid.

Where to start? They are selling decades old tanks - which they just sand down and paint and try to pass off as new. This is the condition of this tank after just a few months. Not only is it totally corroded - but leaking gas to the point I had to have an emergency service call to remove it and put it way away from my house for safety. THEN they refused to refund even though they are LYING about this product and want to send me another tank - suggesting that I put a cover over it or use Rustoleum on it. DO NOT BUY FROM THESE PEOPLE!!! ... show more
