The Wahl Km cordless is much better than the Wahl Super groom cordless dog clipper I used - faster, louder and cut through fur like no tomorrow! However, it is impossible to remove the blade for cleaning as my hands are weak. Also, the competition Wahl 8 Piece Metal Comb Guide Set is not useful as their sizing is not normally used by me (I do 4mm on my dog but their 1st size is 3mm and 2nd size is 6mm!) and to attach the guide onto the clipper is very hard work for my weak hands. I am not a groomer just a house wife who has a very nervours little dog. The ordering system was simple and my order came very quickly so thank you Groomers World.
