My neighbor said it was running on and off while we were gone. They actually said more on than off and they could not get it to turn off. Let me tell you what happened when I called Pools Plus. The Sales Mgr answered and I discribed the problem and he said he remembered all the problems they were having with these switches but I would have to talk to service. Instead I ask to speak to the owner of the business and he refused to let me talk to him. Later that day the service mgr called "Kip" and told me at least 20 times in 5 minute conversation thios was not there problem. I was out of warranty. Can you imagine a company not willing to fix immediately a electrical panel that was inside a hot tub and was defective. What if we were to get electricuted. I just had to turn off the hot tub completely because I'm concerned about a fire. It's full of water and it's 21 degrees outside. I sure would like to speak to the owner about this serious problem. Thank you
