I have a side winder and love it. I usually wait till I am down to a couple of threaded bobbins, then fill all my bobbins which number about 25 with different colors of thread, plus several white and black. I saw it at Walmart for 25dollars. I had a birthday coming and asked my husband to purchase one for me. That was three yrs ago. I am still using it. I love it, I will never use my babylock to wind bobbins ever again. Go for it, you will not be sorry.
