I use it when sewing with my Featherweight as it is easier to use the side winder than the bobbin winder on it. Mine ws a gift, but I wouldn't buy one. I'd but rotary cutter blades of sewing machine needles instead :)

Tried one, gave it away.

I used it for a while, but wasn't really happy with it. I can now wind bobbins on my machine without unthreading, so I just do it that way. Honestly, I think this is one of those gadgets that isn't really worth the expense.

I am not sure if you are talking about the little one but I got one and hated it and returned after couple of uses but I know people who swear by it

Love it!!!!!!!!!!!!

It is one of the few gadgets I have that I really use a lot! LOL My machines don't always fill the bobbins with the same tension. My sidewinder always does. I like it so well, if it fell apart today I'd get a new one tomorow coupon or not! LOL

I got the small (30.00) one and I love it.

I have a viking and it doesn't work with my bobbins for some reason. :( , I also have an old kenmore that is a backup machine.I use it for that one . So Nay I would buy something else.

I have one and love it. The first one that I had put more thread on the bobbin than the one I have now. But I like it so that I do not have to stop and wind bobbins in the middle of a project.
