I already had the tankless version of this and believed it to be the best that a person could own if you need 12 volt powered portable high cfm pressured air. And I jumped at the chance to buy this tank version and was pleasantly surprised that they Incorporated the tank gauge as well as a gauge mounted triggered airchuck. I was also pleased to find that they now use standard USA automotive type quick disconnect 1/4 inch fittings. The older I get the more that I find that it's smart money to buy the good stuff, because when you need a tool/asset to work you don't want to be in a position to say: I should have bought something better...
