I usually check my tires once or twice a month and they need 35psi so I set the air pressure to 37psi. 5/5 Works as it should. I have measured with a regular pencil gauge and then with a heavy duty gauge and all readings were within +/- 1 PSI units of 37 PSI. It took about a minute to inflate each tire from 31psi to 37psi. --- Design --- 4.5/5-Pros - Good looking and comes with a carrying case. The inflator fits snugly into the carry case and closes easily. Cable back into a small compartment. This compressor shouldn't give you any cable storage problems. - Cons - You can see that the plastic sheeting over the display scratches slightly in my photos, but that's not a big deal to me (I mean, you're buying this to inflate your tires, so functionality is more important here). --- Durability --- Not coming back to update this part of the review means my inflator is still working and you should consider buying one.
