My first horse clippers were Andis, and I hated them. I have had Andis blades for my Double K clipper & I hated those blades too! So, I dont see myself ever buying anything Andis again.
On the other hand--I love my WahlsI bought the Wahl Chromado the spring of 2005 and if I had got them before I bought my Double Ks I would never have bought the Double Ks. I have used the Chromado hard every spring, summer & fall since I got them. They are still going strong, though the battery finally started to weaken last summer. They still do a lot of clipping on one charge, but not as much as they did the first 7 years I used them. I body clip all my foals, spring clips on the older horses, and all my show clipping with them. One blade will last me most of the summer, even with clipping dirty horsesI do use a new blade when clipping faces for the shows. Definitely love those clippers, and blades!! Now I also have a Wahl Arco, and they are just as good, though I havent used them much yetthe thing I like about them is they come with a second battery, so I can clip with one & have the other on chargenon stop clipping that way. After having these Chromado clippers I wouldnt buy anything but Wahl.
