Nikkai A31JL Mini 5.8Ghz Wireless TV Audio Video Sender & Receiver Kit - No interferance with Wifi. Compact Size

Purchased to send my Sky+ signal from downstairs to the upstairs bedroom (approx. 5-6 metres away). Delivery was excellent. Ordered on a friday and received the following monday (with free delivery).Set up was very quick. Plugged the transmitter part into the Sky box downstairs, and the receiver into the TV upstairs. NB. If you have Sky, make sure the Scart socket is selected from the Sky settings menu (by default I think it is normally set to off). Point the transmitter and receiver so they are roughly facing each other and the signal should transmit without much tweaking. Select the correct Scart channel output from your TV upstairs and you should see the transmitted picture. Everything works fine, and you can control the second TV using the Sky+ remote control, just make sure the remote sensors are placed in front of the Sky box on the first TV where you'd normally point the control to change the channel.Picture quality is really good. Better than I expected to be honest. Its not HD, but its very acceptable. Sound is also very good. No interference or notable crackling. Changing channels is instant, and you can do anything that you can do on your Sky+ box as normal from the second TV, e.g. pause, record, catch up, etc.One small issue I had upon first set up was a blue screen and low sound. After some mild stressing, I realised that I had not pushed the transmitter jack all the way into the transmitter box. So if you do get a blue screen, check all the connections are pushed very firmly in.I've only had the Nikkai for 10 days, so lets hope it continues to function as well as it currently does.

I reviewed feedback on several similar items before settling on this one as having the best feedabck at price point I was prepared to accept. The sender was purchased to replace a cheap 2.4 GHz unit bought several years ago, which had recently been getting too much interference from other devices to be usable (not sure if in my house or next door).Installation was very simple, and although it took some trial and error to establish the best channel settings and positioning for my home, it has now worked satisfactorily for around two weeks with a Sky HD+ box. As the sending unit is in one house extension, and the receiver is in another, the signal has to go through multiple exterior and internal walls, so the fact the signal quality is not perfect is no surprise. However, it is perfectly acceptable for the 14" TV in my kitchen it was purchased to drive. Obviously it isn't HD, but it doesn't need to be. I think people's expectations for these units may be too high and fail to take into consideration how signal strength can be attenuated by passing through multiple walls.

I see this as £50 wasted. I needed the signal to travel about 30 feet in a single story building. The picture is dreadful and constantly requires re tuning. You tune the units by pointing them toward each other, tune them and remove your hand and the signal deteriorates. Switch off the TV and then turn it on again, the unit needs re-tuning. Walk between the two units and impede the signal and the picture is lost. I have tried all of the channels and there is little to choose between them.It reminds me when you used to have to tune an indoor arial in the 60's. Cost me £50 and I have to get somebody in to wire it in the connection properly....

NO... very dissappointed with this product, bought this to replace an old 'one 4 all' 2.4 unit which produced good pictures and sound but was beginning to suffer with too much other electrical interference. I installed this unit in exactly the same place as the old unit and was eagerly looking forward to an improved experience.....Wrong !! Despite spending many hours trying different channels and orientations the best that I was able to achieve was a noisy picture and sound, plus the IR failed to work at all.... the other problem was that if you walked accross the path of the 2 units it would cause massive interference, the distance between the 2 units was about 6 metres and it was transmitting between the lounge into the kitchen with a 2 metre hallway in between.I returned this item back to amazon using their freepost return system and recieved my refund no problem...I then ordered up the 'Signstek 5.8' system which icidentally was £15 cheaper than the Nikkai and have been delighted with the result. Installed once again in the same place as the other units it worked straight out of the box! ..Have made a few little adjustments to the orientation and settled on a channel that gives beautifully clear pictures and sound and the other bonus is that the IR works which enables me to use the remote control from the kitchen, am really impressed and pleased with this unit.... 5 stars

Bought to a Digi-sender unit that failed after many years good service. This unit works, but does not perform as well as the previous one.Not bad enough to send back, but TV picture rather fuzzy, and unit is very sensitive to interference.PROS. Compact discrete design, easy to install. Inexpensive.CONS. Poor performance, especially as transmitter is only 18 feet away from receiver.CONCLUSION You get what you pay for, I would recommend spending a little more!
