I normally will be the first one to say, in tools, you get what you pay for. That said, I was in a bit of a bind one day, because my very expensive Angle grinder died, and I was half-way through a project that I needed to finish that day on my Jeep. I tried Home Depot, Lowes, and Sears, but they were all very expensive, and I was tight on funds at the time, so I went to Harbor Freight. Sure enough, they had one for under $20.00. I knew the likely hood of it lasting for very long was almost negligible but I figured it'd be worth it just to finish the job I was on (which was very demanding on that tool). Anyway, 2 years later, I am still use my HF angle grinder and it works perfectly. Maybe I just got lucky, but heck, I can't really knock the quality of that little device, and I've abused the heck out of it. Now I treat it as a challenge to see how much abuse I can throw at it before it dies.
