Programmable Controllers?

does anybody use these, i was looking into one called purgro robot looked pretty good, and was trying to find more info on this

I use a iGrow 800 VCS in a greenhouse. Great investment. http://www.link4corp.com/products/igrow-100-series.html

does it do everything is say it will

that one doesnt fit my setup, the one from purgro fits me much better just was wanting more info on that particular grobot

What did you find out? Or decide on?
