Pros : What a dream to use this grinder. Easy to change pads, easy hook up to water source. Cut my grinding time down to practically nothing. Wish I had saved my money and bought this grinder in the first place, rather than trying for the less expensive one.
Cons : Still some water splatter, but a plastic apron helps!
Other Thoughts : I agree with other reviewer: need an intermediate pad for grinding out scratches.
Pros : This is a well-made grinder and one of the best on the market. The magnetic disk system without a center hole gives you an exceptionally large working area for larger pieces. The machine runs smoothly and the water delivery and drainage system is very well designed. You can hook up to a garden hose if you don't want to purchase the water pump.
Cons : The flexible diamond disk set that comes in this kit is high quality and if purchased alone would cost quite a bit. However, it is next to impossible to grind out the scratches made by the 400-grit electroplate with the 600 grit resin disk. The metal disk is so much more aggressive than the resin that the difference is too great between the two. You will probably need to buy at least one intermediate grit. Abrasive Technology (the manufacturers of the grinder) sells a 225 grit resin disk for about $250. Be aware that there are MUCH cheaper alternatives on the market if you shop around.
Other Thoughts : You can't go wrong with this machine. I highly recommend it.
