Simplicity388175A Sidewinder Portable Automatic Bobbin Winder Machine, 120 Voltage, White

I got this because I was tired of having to re-thread my sewing machine just to fill a bobbin. What a treat that it fills the bobbin SO FAST!!! On the machine, I'd start the winding and then do something else while it finished. With this, I don't even have time to pick up something else - its already done! It winds with good tension and reasonably evenly (more evenly than my machine!) - no issues so far. It looks/feels a little on the cheesy side, with what seems like flimsy plastic pieces, but wow! - those pieces work fast! And really, we're just talking about winding thread, for goodness sake - it doesn't need to be super strong, just super functional. And it certainly is that!I use the AC adaptor, and just keep it plugged in. It's a neat little case that closes right up - so it doesn't even get dusty. Definitely a good purchase!

Easy to use and fills bobbin quickly! Saves wear on my sewing machine!

This little bobbin under is a gem. My winder on sewing machine decided to give up. Rather than take my machine apart, I bought this. Works fast. Winds evenly. Low cost. The cord is a little short but it didn’t matter because the product is so useful.

The unit I recieved didn't work properly. There were 2 speeds...on and off. The winding went so fast and would not stop and the thread ended up overflowing to the spindle but the machine continued to wind it. I had to unplug it to turn it off. The little button to push to turn on had no effect in turning it off. Having read the reviews, I took a chance but for the price it should have worked, but felt like cheap junk. Returned.

I was in the midst of making a quilt when the bobbin winder portion of my 30+ year old Kenmore sewing machine decided to stop working. I chose the Simplicity bobbin winder because it seemed to have a few more positive ratings than some others which looked more elaborate and cost more. I received the winder very quickly. The instructions are not very good. There seems to be more information printed about safety precautions and interference with electronics and electronics interference with this machine (?), instead of writing clearer instructions. This took some trial and error to figure it out.I used the adaptor and when my first attempt to fill my empty bobbin failed (totally my fault as I didn't push the thread through the eye), I corrected my mistake, but then pushing the on button didn't turn it on. I unplugged the adaptor and then plugged it in and the bobbin began twirling, but I wasn't holding the thread at the beginning, so the bobbin wouldn't fill up. Eventually I got things going and the bobbin was filled, but the automatic stop didn't seem to want to activate, so without an off switch, I unplugged it and installed my bobbin into the sewing machine and continued sewing my quilt. My Simplicity filled bobbin worked fine.When it ran out, I inserted my empty bobbin into the winder and everything went fine, but the automatic stop did not work. I found that I could just take my finger off of the on button to turn it off this time around. Really, I'm OK with that. I unwound the excess and inserted the bobbin into my machine and the filled bobbin worked fine.So, overall, I am happy with my Simplicity bobbin winder, but I suspect better instructions would benefit the customer greatly (at least this customer).

I really wanted to love this but unfortunately it will be getting returned. Definitely not worth the price. Very flimsy as others have mentioned. The worst part is you end up with a half filled bobbin every time. The winding was tight for the most part but the way it fills the bobbin is just ridiculous. Perhaps it’s my style of bobbin or user error but it’s pretty straight forward. I did read other reviews that were less than stellar but decided to take a chance in the hopes that this time saving gadget would be the ticket to unthreading my machine every time I need a new bobbin.

This product is great. This item is easy to use and convenient. I have always had to take so much time to wind bobbins but this is awesome to use and quickly completes the task. Even as a beginner, this is one part of sewing that is uncomplicated.

This worked well for me - as soon as I learned to make sure the winder tension was tight (turn it to the right). If you don’t do that the bobbin thread will be too loose. It works very fast. I used a regular spool size of thread. It may not work well with large spools.
