Good afternoon. Before I throw these on Ebay, I thought I would put them up on here first. I have (4) Rossmont 4100 Movers and (2) Rossmont Wavers that are less than a month old. I put them on a clients tank and they did not like the appearance of them inside the tank. So, here we are. These things move an insane amount of water! They are controlled through an app on your phone and easy to setup. You can buy these on Amazon right now for $329.95. I will sell each one of the sets for $200. And just so everyone is on the same page, a set would be (1) Waver and (2) Mover 4100's. Let me know if you have any questions.
Sincerely, J
