I'm learning cw, and while it would probably be better for me in the long run to buy a proper CW key I like build things.
If I had to give it a rating i'd give it a 3/10. It's very stiff and hard to move. I have to reposition the alligator clamps every 30 or so taps making a conversation on CW almost impossible. But where it gains points is it's super simple to repair, parts are everywhere, because it's made out of scrap metal, and it only costed me a $1.50 for the coke bottle as the base.
