Viair 400p automatic compressor is the best compressor I have ever bought, everything about it is high quality . This compressor is priced high but it is way better than the cheap compressors that you normally find at the local store. It is extremely quiet and will fill your tires just as fast as it claims. The automatic shut off feature works very well. The only thing that would be better is to be made in USA instead of China.

Excellent build quality and ease of use. First use was to air up two jeeps after a day of trail riding around Florence AZ(one with 32" and one with 33") tires in no time at all!

No complaints so far

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.

Excellent power, excellent packaging, excellent quality.

This VIAIR has it all. It is reliable, built tough, attractive, and works exceptionally well. It is the only portable compressor I would buy.

This compressor is convenient for our boondocking truck camper excursions. I use it to return truck tires back to 80 psi and air bags back to as high as 100 psi while away from civilization and my garage. It fits behind the rear seat in the truck and I like that I can take it out of the truck to bring it on trips in other vehicles too. If I had opted for a truck mounted one, it might have been more convenient for its main use, but then would only be where the truck is.

Great air compressor

I have only used this compressor a couple of times, however, I am impressed. Quick air up time and excellent quality.
