I bought an Andis clipper blade for my dog grooming job for $37.99 at the beginning of August for my new job August 10, 2016. After 5 uses it quit cutting. I cleaned it out, still wouldn’t cut. Had it sharpened but still wouldn’t cut so I took it back seems it was defective. Colorado animal health told me they would not replace it, as they have no policy on blades. Then told me about their own sharpening guy. I bought that blade for almost $40 bucks. Paid $ already to have it sharpened which did not resolve the problem and they want me to pay for their guy to sharpen it? I think not.
