I bought one of these 3 years ago. When my girlfriend's car compressor died I bought a second one for her.This is the best compressor I've ever had for carry-in-the-car use.Some people don't like the screw-on hose connector. I think that's a strong advantage, and it was the reason I bought the first one. It makes a solid connection that won't slip off.As years go by and things get a little cruddy, I found it's helpful to spray the inside of the threaded hose connection with some silicone lubricant. Don't use regular oil because that will attract dust. The silicone lube makes it easier to thread the hose onto your tire valve.
