I use the pumps, they're great for the price.
The waver on the other hand is complicated to use imo. I have 2 of them they're setup, but not how I would like to be. I spent a lot of time to get them configured the way they are. Compare them to the Wav by neptunes, the Wav I got setup in less than 10 mins to my liking and to control the pumps is very simple.
Going forward if I want to control the pumps, 100% Neptunes Wav.
If I just need to plug in some pumps and let them push water, I would not hesitate to buy Rossmonts.
