I have the Wahl Chromado cordless/corded clippers & I love them--but then I bought them for something very specific--clipping jaws & bridle paths. I can use these just out in the corrals to tidy the horses up, without having to bring everyone in for clipping with the double K's. They are great for that; I've also used them for clipping bellies on the due-to-foal mares, & I've clipped some of the foals when I want to see what kind of a croup is hiding under all that fuzz. I wouldn't want to use them for doing a full body clip for showing--that's what my Double K's are for. I find the blades last a really long time, even when clipping dirty horses. They do an okay job, but just not quite a smooth as the Double K's.
When I went to buy these cordless clippers I did initially look at the Pro series clipper. I could have bought it for $99 I think it was, and the Chromado was about $195. The Pro felt very light & I felt I'd be disappointed in it, so I decided to go for the higher priced model. I'm glad I did--I'm overall very pleased with this one.
