I have two of these and they work great. Never any problems with the small addi machine. On the addi king size it wobbles when it runs. I made the mistake of tightening the attachment screw to the machine and I did this on both my machines. It snaps off the little tip of the piece you screw it into. I tried e6000 and also super glue but it is not strong enough and it breaks again. I'm waiting for replacement handles to come in the mail. Gonna try again but will need to figure a way to support the bottom of the machine so it doesn't wobble so much.
I believe it can, I tried it on mine but... I did not line up the little pegs properly and I rushed it, I really wanted to try it. Lol and broke the gear on addi. Now I am ordering a new part. But it does work on both.
