Review on Foredom ABCD Foot Control by Mark Powell

I purchased this item in the hope that it would help control the speed of my Dremel 4300 rotary tool Tool has its own speed controller. I tried setting the tool to both max power and medium power and in both cases the Dremel 4300 did not behave as expected. Instead, the foot pedal basically works like an ON/OFF switch for the Dremel 4300, no matter how hard or light I press the pedal. On the other hand, I have a WEN 2305 (also with its own speed controller) that allows the foot pedal to control its speed. So the pedal appears to be working normally, but results may vary depending on the instrument you're trying to control.
