Leaks air

I only bought this to clean dust out of my PC, and whatever else I may need it for in the future. I used it at about 30-40 PSI & noticed air leaking when not in use, as others have said. It also had a ton of oil around the handle. I wiped it off a few times. Also, it was quite difficult to attach to the hose. It got the job done for now, but I would not buy it again.
