I have used professional nail grinders before but never had one at home. When I used my dremel on our x-large long haired dogs it was a constant struggle keeping their fur from getting wrapped up in it. The nail grinding accessory is easy to add to the dremel and has literally shaved off 80% of the time it took to do their nails before. It is just as nice as the professional groomer grinders I've used, maybe even nicer.
works better than the older version of the product
i had an older version which attached to my dremel tool, but it finally wore out. I like this one so much better. The old one had little round holes that you rotated depending upon the size of the dog's nails, if you were not careful the nail could get sucked in, I have chihuahuas.
