I guess I get set in my ways and resist change. (Translation: old and set in my ways) LOL But then, I keep 4 clippers in holders on the wall, each with a different blade. That way I don't have to change the blades out. And the clippers don't over heat as I keep changing which one I am using.
I like doing that. Back before I did my own grooming, my one dog came home more than once from a professional grooming shop with bad clipper burn. I hate to see that happen to a dog. It's got to be painful -- it required vet care more than once.
