I used Quidad's Tress FX, over a year ago, and had disastrous results with it. It left my hair feeling dried out and my curls felt hard and crunchy with it. I have only tried one Quidad product so I don't know how well their products perform, but I don't have any interests in revisiting Quidad's line again.
