Mikki pet products (sold in most pet shops) are a waste of money. They are expensive and do not work. I have bought nail clippers and scissors that do not work. Having bought these again made by a different manufacturer they do work. It is not fair that Mikki make poor products because they make the dog owner feel like they are using the products in a wrong way when it is the rubbish quality of the products. Cutting a dog's nails is not easy at the best of times, so when the clippers don't work too it makes for a lot of stress! Don't give Mikki your money, go on other reputable grooming websites and buy their own manufactured products for half the price and 100 times the quality. I only gave Mikki a star at all because actually their brushes are ok, but then who can ruin the manufacuring quality of a brush! Don't waste your money on Mikki pet products.
