UPDATE: I liked this compressor especially its accuracy and speed at 110v. After about 3 years it broke a few weeks ago. I haven't used it that much, maybe 3 times a year on two machines. Tires less than 100pcs. I was filling my friend's truck tire and it started making a strange noise and the pressure wouldn't come out. Now when I shook it, it rumbled like something broke inside. Very disappointed. It was great while it lasted but not too long in my opinion. I will NOT buy a new one, I will look for another brand.------------------------------ ----- ------------- -------- Exactly what I needed. It's great to be able to use mains electricity (120v) from your home. I inflated the tires VERY quickly to 120v and was amazed at how accurate the compressor gauge was. I checked the tire pressure with TWO independent pressure gauges and then with the pressure gauge on the compressor. Surprisingly, all THREE gauges gave the SAME reading at 35psi. Extremely accurate. I can trust that, unlike the sensors on some of the other cheaper portable compressors I've had. Comes in a nice very well designed cloth bag to keep everything together. I keep it in the car. Worst of all, a flat tire needs repairing and the spare tire is under-inflated. This compressor runs up to 60psi, which is what the spare donut tire on my car takes so I can pump it up when needed. I'll get a second one for another car.
