Review on Universal Control Pedal Sewing Machine by Kelly Caballes

The product has a rheostat but it does not work. The sewing machine is either turned off or fully turned on as quickly as possible, it cannot be made easier with this pedal. I have a broken or horrible design. It has a variable speed rheostat, black knob in picture. However, due to the design, it touches the head of the screw that attaches the rheostat to the foot pedal, completing the shift, bypassing the variable speed entirely. Will work for you if you don't care about variable speed.
