Anyone had any experiences with SystemsProtect?

Since I retired, I am hoping to avoid any forseeable problems with the eletrical items in my home. For $383.00 a year, everything electrical is covered, after a $75.00 fee for each service call. This plan also includes replacing non-repairable items, like my central heat and air and kitchen appliances, for the same annual price. SystemsProtect is a national company thats been around for a long time. Question: Are you familiar with this company? If so, any personal experiences you have encountered with them would be greatly appreciated.
