On the whole very pleased with my purchase. The switches look good and modern. You push them in to send a signal to the receiver. They don't toggle up and down like a normal light switch.The instructions aren't too clear, but it was very simple and intuitive to connect it. I live in the UK and fortunately my electrics were compatible where I needed to wire it in. This would not work in a switch with only a switch live - it needs both a live and neutral into the existing switch and back out.I can confirm you can wall mount these into a standard UK back box and managed to fit the receiver behind. To screw it into an existing back box you need to pop the switch part off the front - I did this by putting my screwdriver in through the screw holes from the back. When putting the face plate back on, it did get stuck in though - other reviews say this can happen if you have fixed the back part too tightly to the backbox. I eventually managed to sort it but was a bit tricky to get the plate off. It would be the same if the battery needed changing too in the light switch.

I had a big building job a few years ago (an upstairs added to a bungalow) and to save money I just had the basic electric fit of one ceiling rose per room.Later, having then used those to fit ceiling fans for the increasing hot weather I was left with a dilemma. No access to the downstairs ceiling void for extra lighting, and because off the shape of roof trusses upstairs, virtually no way of fitting a two-way switch in the bedroom by the bedside.These things are great. Downstairs in my lounge I now have a combination of four floor and table lamps plugged into sockets, each with their own receiver unit (which I fitted inline inside some neat little plastic junction boxes from a DIY place) and all turned on/off together from a single Nineleaf radio wall switch.Upstairs in the bedroom I fitted downlighters in the ceiling (receiver in the loft space), controlled by a switch on the wall just outside on the landing for entry, and a 2nd switch by the bed. I was also able to wire into circuit a cabled wall switch just inside the room, with a dimmer. So the dimmer tends to get left on my favourite level, with on/off duties performed by the two Nineleaf switches.All of that lot came in for the same price as just one MK switch and receiver. Kits come ready frequency-matched, and when I added extra receivers for downstairs, they were easy to pair with existing switch. I'm very happy.

As a concept these are very effective, you can put light switches wherever you want them without having to channel cables (the time saving probably justifies the cost).Installation was reasonably easy but not without issues.Pairing is done by pressing and holding a button on the receiver. What is not clear is that there is an indicator light under the surface of the receiver (not immediately obvious) that does the required flashing to tell you when it is in pairing mode.The instructions are not that clear. For instance the instructions indicate that pairing a second switch to an already paired switch & receiver can be done by pairing the two switches; in practice I found I had to pair the second switch to the receiver, which fortunately was accessible once I got the ladder out again. (If I had buried the receiver in the ceiling void, that would have been a major pain.)The switches can be stuck with adhesive strips to any flat wall (i.e. not to textured wall coverings). It is more effective to screw them either to the wall with a couple of rawl-plugs or to the electrical box to which the conventional switches had previously been fixed - the fixing holes in the back of the switches are the right distance apart.There are three cautions if screwing the switches to existing electrical boxes.1) To get at the screw holes you have to remove the surround using a screw driver and tiny slots on the bottom edge, then pop the actual switch pads off their mountings. With two (or three way) switches you worry a bit that you might snap the switch pads2) Once you have removed the switch pads the actual back - which you secure to the wall is much thinner than the conventional switch being replaced; therefore you have to either shorten the screws or take care not to trap the wires in the wall.3) Because the switch back is quite thin it is quite possible to warp it if the wall is not absolutely flat or the cables in the wall box are not lying flat. If it is even slightly warped the switch action might not work.However once fitted it all all seems to work well; I have replaced my hall light with a couple of wireless switches and the landing and corridor lights with three switches.There is a possible safety issue for those who may later maintain the system without any awareness. Normally when working on a lighting unit some people just ensure that they are "switched off". With these systems of course you have a permanently live feed into the receiver unit which will in most cases be in the lighting unit or close to the ceiling rose. Before working on them you need to remove the distribution fuse (as you should when installing).My only concerns are how long the switch batteries last and how durable they will prove to be. (Some alternative systems don't require cell batteries as they are powered by the switching action.)Given that these systems are proprietary, I might be sensible to buy some spare units. It would be a pity to have to replace the entire system because I cannot replace a single part should it fail.

The install was very straight forward. Physical wiring was simple enough and to pair the switch to the receiver was simply press the button on the receiver for 2 seconds until it flashes red then press on the switch, it was that simple. The QR code for the IOS app didn’t work, however if you download the Tuya app that works ok. Connecting to the app was straight forward too, hold the receiver button down for 5 seconds until it flashes green and then connect to it on the app. As like everyone said, make sure your wifi is set to 2.4.

Hoped can replace my light switch within 5 min. Problem is (and was not aware) that my switch is not standard. Had to ask electrician advise. It took him 5 min to make switch working and since I'm in love in this idea of wireless switch.
