Yeah the spark never bothered me. Good pumps. App is crap. Wifi is crap. Strangely enough I had both the SCP-90 and MCP-90. I swear the MCP controller puts out less power than my SCP controller. Same pump. You can swap the controller between different pumps. They all work together. When I move the SCP controller to the pump that came with my MCP it started pushing water like the SCP. I found the digital display to be worthless. They lock down the controller if you use the AP. So, you can't even push a button for feed mode. I hate these controllers and apps. But great pumps.
