Query: Worst piece of Junk I've ever owned...

Listen,If you preform out on a weekly basis I urge you not to buy this sustain pedal. The rubber grips on the bottom and top of the unit fell off of mine after a week of practice and three shows. On the very last night that I used this product the spring mechanism went all wackadoo and required an additional tap to release, which, as you might imagine, was not the easiest way to finish a gig--especially in front of a packed house. Those who are going to buy this pedal should only do so if they are looking for a "throw-away" accessory, perhaps for their child who is still trying to figure out wether or not they are interested in keyboard studies. If I had a choice between buying this pedal again and smashing myself in the foot with a hammer I'd probably chose the latter...at least with a cast on your foot, your audience might be forgiving of botched chord transitions.
