Pros: Auto-shut off. Set desired psi. Auto 12V cord included. Light weight.
Cons: Short electrical cord.
I just bought one today on sale for 49.99 at my local hardware store. I will use it to fill the tires on my truck. Saw on other sites that many complained that the power cord was too short, but I had an extension cord so I did not see this as a problem. It's a small and lightweight unit. I like that you can set the desired psi and that it has an auto-shut of feature. It's kind of noisy, but I don't think my neighbours will mind since I won't be using it everyday.
