Review title is Wish it had a slightly slower speed or finer grit on the disks [SEP] This machine is similar to the ones used in nail salons except the circular disk is smaller. The only thing I don't like about it is the speed. I wish there was a slightly slower one. You really need to be careful with this and use a light tapping motion at the area you want to file down. It works, but even though I knew to tap after watching the manicurists, it goes much faster than theirs and burns quickly. My feet were a little sensitive that night. Or perhaps if the grit on the disk was finer the speeds would be ok? It arrived on time and was packaged well.
