I just bought one at Hancock's when I could use a 40% plus a 10% coupon. Haven't opened it yet. Clerk in Hancock's said she loved hers. There were 2 brands. I bought the original Sidewinder and now Simplicity has come out with one. Same price. She hadn't tried the Simplicity so I opted for the original. We'll see. I use all white bobbin thread in my embroidery machine and the thread winder on it doesn't wind tight or even. Also, the better wound your bobbin is the better the machine sews. :)
