I just purchased this and it did NOT work as the air was pouring out at the air tool attachment adapter. Turned out the air coupler on the tank was defective. Fortunately I had a neighbor who let me borrow another coupler and everything seemed to work as it should. It is on the quiet side. the wheels are ridiculous cheap. the handle is nice. I guess I should have sent it back, but it was a large item for apparently a relatively small defective part. I had to purchase a new one to make it work. I hope the internals are not so cheap and or defective as the external appendices seem to be.
