Assuming Jebao has done the same thing as in the Vortech (a reasonable assumption ), the ability to synchronize modes across multiple pumps can be quite useful. OK, sure, I suppose one could adjust each controller separately to achieve the same effect, but with wireless synching it is much easier.
I think there is a use for it... I don't use the wave functions but like I mentioned earlier a more impressive setup would be a simple controller capable of multiple pumps. Sell me a master unit for a few bucks more and let me buy individual pumps as needed. I think we can all agree that we have enough controllers.
