First of all, it is very light, quiet and easy to handle. It charges via USB, so you don't have to fiddle with cables when you go to the tire for gas. It also didn't get as hot as other portable compressors I've tried. It's supposed to be good to 150psi, but I haven't tested that. The only minor issue is that I set it to auto stop at 36psi, which according to its built in sensor it did. I then check the tire pressure with my personal digital pressure gauge and it reads 40psi. Since I prefer to have too much air and then let it out if necessary, I will leave the product as the pluses outweigh these slight cons.
