quality grinder with good performance. I bought them before and use them at work (body repair). I usually use it for about 3-4 years, then replace it and use it at home until it gives up. Most people should be very happy with this grinder unless they are tool snobs who need a brand label and want to spend 2-3x more. Note that these types of grinders require a large volume of air to function. Don't expect to use one with a 10-gallon tank or an oil-free compressor. Sandpaper can also be expensive, as it's usually only available at auto body shops or online. It's not a very handy tool for a homeowner, but I've used mine to remove all stains from an 18' x 28' cedar deck and the grinder still works!
