i really like mine alot. it's breeze to use and i don't have to un-thread and re-thread my sewing machine every time i need a bobbin wound. i don't sew as much as some so i don't wind my bobbins in advance and it makes it easier for me because i can wind mine as i need them. i bought my bobbin winder before i bought my new sewing machine and i honestly haven't used the bobbin winder on my sewing machine yet. if you sew alot, it would be a great investment and major timesaver.
