Just DONT
no instructions or paperwork of any kind.<br /> Not that it takes a genius to plug in. But it arrived just tossed in a plastic bag.  Not reassuring.  I put them on and tried all the settings and the best I got was a fried ring finger. Wish I was told TAKE OFF RINGS!!!<br />SO off with the rings, try again, best result was a nice shock/burn under the contact on the back if my hand.<br />Best part: They accept NO RETURNS.
