I'll second (or was it third or fourth) the poor design of the Tempo King pedal. I picked up one and have tried to make it feel good - futile. It's too wobbly. I replaced the leather and it's still just too dang wobbly. It will 'swing' from left to right with no solid feel under my foot. I'm not used to having a pedal that wobbles and shakes and shifts when my foot rests on it. Bad stuff.
I use others; speed king, dw5000, dw7000, blah blah blah.
