If you have a machine that does a poor job filling a bobbin, it sure is worth it. Lousy bobbin = lousy sewing experience.

I love mine! So much easier than having to re-thread my machine after filling the bobbin. I make sure I have 2 spools of every color of thread - one on the machine and one to wind bobbins.

Love mine. I got it with a 50% coupon, cuz I thought the price was too high for what it was.

I wouldn't trade it! The bobbin winder that came with my Sweet Sixteen is a pain, and I can wind my size M bobbins on my sidewinder.

I bought one...it was a nightmare to get tight even bobbins...so I took it back and bought more fabric...thinking back why would I need one when I have 9 machines that have one on each machine

I love mine and find it saves wear and tear on my sewing machine!

I love mine, if you are running it on batteries, and batteries get low, it can cause tension problems. I usually run mine off the plug in and only use batteries when I go to class, or retreat. winds better than my machine winder, and I do not have to rethread he machine.
