Simply because the remote has a lot of lag, work toward the receiver (yet at 2.4GHz) for a chance that it captures, if it captures and it in no more than 3 meters, with no obstacles between the transmitter and the receiver
I had chosen this remote to replace aging médion X10 remote control, the latter, however, still being very responsive and comfortable.
When I saw 2,4ghz, I thought great, a high-frequency radio remote control, (I did not want to infrared), so I have ordered two.
Both models have the same worries, the same defects .... all is said.
Result: return to sender.
In short product not buy to avoid disappointment.
