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 do not 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
