Unit pumps well up to about 65psi on boat trailer tires. Have yet to test up to 80psi on HD truck tires. It's not too loud. The double cylinder appears to be VG. The cord is short for larger vehicles, especially when using battery (some lighters may not have capacity). The main complaint is the gauge reading 5 lbs too low. So I can't rely on that and have to confirm it with hand-held measuring devices. The cooling fins on the cylinders are useless and are painted to look like aluminum but are actually plastic. You don't need anything else. Toolbox and more quickly recognize the value that is being put into the design of the pump. So far I like it though and I find it a good upgrade over my slime pump which doesn't lower the pressure or the continuous pumping time.
