Query: No power after just 4 months of use

The wireless system is just horrible. For the brief moment of use which is barely four months, I had to deal with statics and loss of signal from the main unit constantly. The distance between them were maybe 8 to 10 feet at most and signal kept dropping with static. Then the power went out on the unit that connects the rear speakers and took a month and a half to repair. Its a total waste, I'd spend little more money and get a better one that works!!!
