I thought it was hype but they really do take the blanket off the tone; the stock Gibson pots are awful or used to be bad.
I have the in most of my Les Pauls and my ES333. I had them in my Firebird.
Update...love the kits! My les paul is just a monster after the installation of the RS kit! Much more dynamic and clear! Same with my firebird...I do believe every guitar I get from now on will recieve the RS treatment!
