After waiting for nearly 2 months for it to be in stock, I finally got my RKL. This thing is great. For simple tasks I do not know why anyone would pay significantly more money for some of the other controllers. Currently I am using the system to run my lights, my heaters, a fan, and a koralia evolution After receiving it, I was able to have it up and running in less than an hour. The setup was simple, and the manual was very helpful. Anyway, I figured I would give my 2 cents since all I typically read about are the apex controllers.
