I had a chance to use the 400P Auto for the first time after airing down my 33" tires. The 400P Auto comes with a pistol grip nozzle. The only thing about the pistol grip is that you have to hold it down to get air. Unlike other nozzles that just lock on to your stem. The air pressure gauge gave me an accurate reading while filling the tires. I aired down to around 20lbs and it took me about 10 minutes to air up all 4 tires to 40lbs. The unit automatically shuts off when not adding air to the tire which helps with not overtaxing the unit when moving between tires, etc. And auto starts up when nozzle lever is pressed. The unit is relatively quiet and was not very hot to the touch after filling up. I struggled with trying to attach the quick connect pieces but maybe that is just an issue for my hands.
