One of the UV diode on my Hydra 26HD burned out. AI wanted me to send it in for repair but I have no spare. I used to have AI SOL BLUE with burned out diode after less than two years. AI sent me the puck to repair. I also saw, AI sold the puck replacement for Vega. I am not sure why AI does not sell puck for all models anymore. It looks like AI customer service is good for responding email but not selling parts for replacement. According to my opinion, their products are not reliable at all. What are your opinions?
