I have a Metrolux II timer and it is hard for me to believe that anything could be better, but the caveat is that I have never used the RHdesigns. But the Metrolux does everything I could ask for and more, including the ability to function as a shutter tester.

Is the timer of the RHdesigns also based on light integration?
