I have had the heater issues myself. It is quite shocking that one of the big names have not come up with a good quality heater. I guess the RKL's and Apex's are supposed to keep these heaters in check , but even the controllers may be a false sense of security . The controller won't stop a glass heater from exploding or a heater from from failing . A controller only turns an outlet on and off. If the heater itself is broke , there is nothing the controller can do about that. Having two heaters is better than one , or is it?
