Nothing detail related. Harbor Freight has tons of budget tools/equipment. You could literally pay 1/10 of the price at Harbor Freight for tools and what not, but what you generally end up with is a disposable tool. It's kind of a toss-up. I've gotten some pneumatic tools that have lasted forver and some that have died in a day..but considering what you pay for it, you can only expect then to last that long.
