I have owned both the ripcord and the QAD ultrarest, and I got rid of the Ripcord. The ultrarest is the only rest that will be on my bows. The main difference between the two is that the ripcord falls whenever the string comes forward even when you have to let down slowly. The QAD only falls when you shoot, if you have to let down at full draw your arrow wont fall off the rest like it will with pretty much any other fall-away rest.
