These are almost as good as Amope rollers
The refills do fit into the Amope pedi perfect very well. The packages tell you the extra course have black sides and the regular have blue sides, so that was helpful. I just don't know how well the textured filing stuff it's made of will last. I feel like I'm going to be changing them out sooner than I would like to. But they do work and they do file away peeling or dry skin. I don't regret buying them.
