Small, easy to use,  USB powered. [SEP] This nail drill is exactly as pictured. It has an on/off switch and an intensity level setting.  It comes with lots of attachments and even several sandpaper pieces to use.<br />I used it to remove stubborn gel polish and I've used it to prep my nails for press on nails. I like that it's small and basically the size of a highlighter. It has a little weight to it but it's easy to hold and use.<br />It powers through a USB cable, it doesn't come with a wall socket.
