Everyone seems to go for the huge or bigger brand named products when Mastercool is also up to par with quality as well, and in my opinion just as good at a much lower price! I do not see how anyone else's recovery tanks could be any better built than these! Very solid tank, good valves and it meets the requirements which says alot about their quality! When you stop and think about all the freon sold in disposable tanks that are made according to federal and state requirement guidelines to contain the pressure of the gas that they hold and are completely safe! How can a recovery that's made from what seems to be much heavier metal, both in weight and strength be inferior to a gas that comes sold in a much thinner and lighter tank? In refrigeration equipment, quality is always a must and I have to say that this tank meets if not exceeds the kind of quality you would expect for years of recovery and at a lower price than most! You cannot go wrong! 5 stars and no less!
