I doubt we will see Vortech knock offs tell all the patents they hold on the MP's expire. Echo tech is very aggressive in product protection rightly so. I feel your pain tho. I have 6 AI's and dual everything else on my new tank. It is expensive to do it top notch but if you do it like you did ,you don't end up with a closet of unused products like I have. But in the long run you get to say You only had to buy it once !! Lmao.
