I bought one recently and was disappointed because it doesn't do such a great job. It winds the thread a bit too loosely for my machine. Also, it is so lightweight that you have to hold the thread spool with one hand, keep the bobbin thread moving up and down (to evenly thread the bobbin) with the other hand, and hold the entire winder steady with yet another hand (3???, ha ha). Not worth the time, money or aggravation. Money wasted in my opinion.
