Ratings and Reviews for  Ancol Ergo Maxi Knot Buster

Only 4 stars cos they blunt easily after only 5-6 brushes IF your dog has a coarse coat..They don't make sharpeners for the blades so you have to discard when it becomes blunt...Shame really..That said there is nothing like these on the market for getting rid of undercoat and knots. They are superb.
