Great file, BYOP (plug)
So far, so good.  The tool doesn’t come with the wall plug piece. I’ve noticed you’ve got to use a usb/base wall plug that’s in good condition and/or not too old. I thought it was the nail file that stopped working on me, but when I swapped wall plugs, used my sister’s iPhone cube, it worked just fine. Before that it would just spin for a split second and stop.
