I have been wondering about this for a long time, why do you have the blaster and the sensor both on the front of the device?
Seems to me I will almost always be arranged, A B C, where I am A sitting in a chair, B is the box, and C is my AV system, so that sensor on the front and blaster on the back would work much better. Either that or the box will be in with the rest of the AV system so the blaster is pointing away from all the stuff I want it to control.
