Harley Benton Speedy Stringwinder

Really nicely made. It goes both directions so it's not just winder it's unwinder too :). It has little string scissors attached that are available with just one switch. And the bridge pin remover on the back side. Part that go on the tuning peg is attached with magnet and can be easily removed. I'ts well worth the money.

Addition: It broke after a couple of uses. It's just not strong enough to handle a lot of winding. Battery is also crappy. If you charge you battery it will maybe hold without using it couple of days. Each time I had to change strings I need to attach it to a power. What's the point of having battery operated string winder if you need to plug it each time you use it.
