Hello I am new to the forum. I am thinking of upgrading my aqualink rs rev. M to the new Iaqualink. I have a pre 2007 model so I will need the more expensive up grade. My question is does anyone have one. How do they like it. Controlling the pool from your iPhone sound neat but is it more hype than function. I have a rs 8 but none of the models say how many items they control . Thank you Stan.
