I bought this unit to send video across my living room from a Pioneer receiver to a Benq projector; a distance of around 14 feet with line of sight and no obstructions. Here are the pros and cons for this unit:
PROS 1) Relatively inexpensive. Actually, I thought £200 was rather expensive to replace a 14 ft cable but that was my choice and I couldn't find anything else at this price. CONS 1) There is noticeable noise on the picture at this range. It's not totally unacceptable but it is visible. It is not HD quality at this range. If anyone walks between the receiver and the transmitter the picture degrades severely. 2) The pairing of the transmitter and receiver when signal is applied to the former takes ages. Around 25 seconds at my last count. 3) Both units get incredibly hot. You cannot pick up the receiver if you touch the metal parts. If this was in an enclosed space I would suspect it could be a fire hazard. 4) Not sure whether this is an issue with the Nyrius or not (but it only happens with this unit involved). If I have a Apple TV -> A/V Receiver -> Nyrius -> Projector then around 20% of the time the ATV picture will become corrupt and shows mainly a green screen. The only way around this is to turn all the devices off and power up again.
