I liked it until the cheap plastic parts inside broke.

Note to all of you having trouble with the upper piston bumper "shattering". The wrong lubricant will do this. The part in question is nylon - which is an excellent choice for this application, as long as you don't expose it to aliphatic or chlorinated hydrocarbon solvents. If you do, it's toast. That's not the tool's fault. That's user error. Use only the proper air tool oil, The proper air tool oil is NOT WD-40, Marvel Mystery oil, and especially not spray cans of anything, like carb or brake cleaner, ( I know, but you'd be amazed at what folks spray in their air tools, thinking they are "helping it work better".) Also, I'd avoid the cheap Chinese oil from Harbor Freight. Just buy the right stuff. It only takes 2 or 3 drops every use.
