Query: Works when IR extenders fail

I was trying multiple different methods to extend IR into a different room for the stubborn Time Warner cable boxes. Every IR extender solution I implemented either would drop button presses or just not send them. I tried this solution as a last ditch effort and it works like a champ! The only thing I had issues with was repeated keypresses seemingly being sent to the cable box. I read the FAQ and backed the emitter station away from the receiver a little and have no problems at all. I returned over $100 in in-wall IR receivers, controllers and emitters and now solely use this.
