I have one. It was one of the quietest that had a sound rating. It is
still a compressor and is noisy but quieter than any others I've
used/heard. While it does have a handle and can be carried it still is
heavy but I do heft into the back of my jeep and take it to work sites.
It works just as it should and never has needed any service. The ball
vale drain is easy to work but it is loud when "dumping air" and works
so fast that it freezes the ground below it.
The regulator works well and I like the two connectors.
All in all, I have NO complaints and would buy again.
