It works just fine, but for a motorized tool, I expected it to spin more like a drill.  It doesn't. As far as speed is concerned, with the same result, I could keep using the $2 peg winder found at my local music store.

However, when compared with a standard peg winder, the powered string winder is steady and smooth. It doesn't snag or bump into anything. Minus the speed factor, it's a good tool.

Do I like the powered string winder? Yes.
Will I continue to use it? Yes.
Do I recommend it? No.

I recommend purchasing a powered screw driver (c $15) and a peg winding adapter (Duck's Deluxe makes one for $5, Dunlop makes a 'turbo tune string peg winder' for $7).
