[MENTION=759]Hijinx[/MENTION], first of all, I love your "Scent from Glade Air Freshener"
For sure Harbor Freight fits a niche, and in a pinch you can get a disposable tool for almost free. I've used them many times over the years. E.g. making a custom adapter or wrench where I had to weld something together because no tool existed, I don't feel guilty trashing the bargain tools.
I've also had HF tools literally break on the first use, not even fit on a nut, and in the case of the angle grinders, only last a few minutes of run-time. You get what you pay for in terms of general quality, the purity of the steel, the accuracy of the castings and forgings. A big redeeming aspect of HF is their return and warranty policy is top notch. In the case of the angle grinders, they failed so quickly I kept going back to the store to get a new one. After the 3rd one failed I simply returned it and bought a good one, and that one has lasted for years and still going. Now I tend to "buy once, buy for life", it's just easier to have a tool work reliably than fuss with warranties and returning and job down-time. That cuts into my beer time, after all.
*edit* congrats to me for my 100th post!
