Review on 30 lb MASTERCOOL 62010 Gray/Yellow Refrigerant Recovery Tank - No Float Switch, ¼” FL-M (7/16-20) by Andrew Lyons

This is a very good recovery tank. It is approved for connoisseurs and filled with nitrogen (not evacuated). Just remember to suck it up when you're ready to use it. Better than my tanks I get at the supply store but hey none of my other tanks have let me down so I guess as long as they work they're good enough. It's nice and shiny if that's what all HVAC boys care about. Maybe your wife doesn't mind so much in the garage. Haha.
