light and sleek [SEP] i have tried several e files i pretty much enjoyed them all this jane choi nail drill is much smaller than my other portable nail drills i tested it side by side thinking the jane choi would be not as effective as the others because of how light it is to my surprised this nail filer is just as good as the other ones it is smooth and has little to no vibrations this a favorite among the nail tech at my salon it is sleek light and smaller than other portable e file with external battery in the market
