Query: Under priced for what it does

I am using the Next Generation Remote Extender (plus extra battery/transmitter)to control a Directv remote and Pioneer Elite DVD player located in a bedroom closet. There are 3 closet/bathroom walls between the living room and the location of the "flying saucer" base station. There is a slight time lag but so far the system has worked flawlessly. No programming required! I did have a Universal programmable remote with rf blaster (which has now been recycled) and was a pain to program.
