content: These combs work well with our Andis clipper, they make it much easier for us non-professionals to achieve the desired length of cut for our dog's fur. Nice to have an assortment of different lengths to choose from. The issue here is that once you take these out of the package, you have nine combs laying around, no way to keep them organized by size or store them all together. I would have gladly paid a buck or two more if it came with some sort of case or organizer that would store the combs in order by size. When you have your dog up on the grooming table, the last thing you want to be doing is trying to figure out which size comb is which. But the combs themselves work fine, easy to take on and off the clipper.
