check ebay for their site
Why would I need to check Ebay for their site when it says it right on the bottle of the picture you just posted?
I have a tank from Poly Performance. I have not had any issues and I've had for 2 years. The only thing it doesn't have are gauges but I just go by how heavy it is to tell if it is empty or not.
I could live without a guage for $174 as appose to $370
