I bought the Sidewinder with a 40% off coupon at Joann's. I love gadgets and loved the concept of this new little machine.
Here's what I discovered:
When the top is open it puts the center of gravity off and you have to hold the base with one hand to keep it from tipping backwards, or prop it against something during use.
You need to unthread your machine to use the thread if you run out of a bobbin during your project.
The pin that holds the spool of thread is thin. When the machine is turned on the thread starts spinning so fast and wobbly, it rides up the pin. I had to keep a finger on the spinning spool to stabilize it while winding. For those of you keeping count, I'm now using both hands while winding a bobbin.
Overall I found it light, cheap and a little noisy. For $20 I'll stick to my old habit of winding bobbins on my machine. I returned the Sidewinder for a refund.
Just my 2 cents, Dianne
