I don't know what I would have done without this little gadget. I couldn't afford t he stitch regulator... and this is wonderful. I use the pulse button for quilting. I marked 2 dots at 9 o'clock and 12 o'clock.. I use the 9 o'clock for bringing my bobbin thread up. and the 12 o'clock for quilting. I JUST LOVE IT !
I love the Speed control and it is much easier then using the handles to squeeze the foot control. But I am on my second one and it is acting up. I slows down or just quits in the middle of quilting. If i move the know back and forth and unplug and plug it in again several times, eventually it will start to work again. And this has happened with both of the controls I have purchased. I have emailed Grace twice to ask for advice but they are not responding to me. But it is great when it works.
