Smart looking switch, and finally replaced our broken one!
Our old dimmer switch finally gave up the ghost and stopped working altogether, so we replaced it with this brushed steel one to match the rest of the fittings. It looks ever so smart and much more modern than the old plastic one we had!Fitting it was straightforward enough since my husband knows his way around basic wiring, though we did have to swap out the old plastic back box because this one is a bit deeper. Definitely worth keeping in mind if you've got shallow walls!The best part is the intelligent dimming feature. Our previous switch used to buzz and flicker terribly with modern LED bulbs, but this one lets you adjust the minimum brightness level. Once we sorted that out, the lights went completely silent and smooth—no flickering at all, even when dimmed right down low for watching telly.Very pleased with the quality, and just glad to finally have a working light switch again. Will be buying a few more for the dining room next!

Smart, smooth and stylish
Really pleased with this dimmer switch. It looks smart, feels well made and works smoothly. The dimming function is easy to use and gives much better control over the lighting. A great upgrade that looks modern and feels like a quality product.

Cheap but it works .
This product is fine. It works and it’s easy to fit. The button itself and the push action to turn it on and off are very cheap feeling however which lets it down as it doesn’t feel solid or well made at all. Time will tell how long it lasts.

Nice dimmer, but beware if you have a lot of fixtures (10 or more)
I already had a couple of these in my house, and decided to get a couple more to replace old dimmers that didn't work for LEDs. Unfortunately after installing them I realised that there was a flicker and then failure when one set of lights was at the maximum brightness. After consulting the instructions I realised that they are only suitable for a maximum of 10 LED lights, and I had just hooked it up to 13 downlighters. The circuit with 8 lights on it worked great.I have swapped this out for a higher rated dimmer from another brand and moved this to a circuit that has exactly 10 downlighters on it, and unfortunately there is still a slight flicker at maximum brightness so it has to be turned down a little. So I would recommend it, but with the caveat that I don't think it works well if you've got 10 or more lights.

Reliable switch
I’ve had this light switch for approximately 4 years and have had no issues whatsoever. It dims the lights smoothly with no flicker or noise, and has remained reliable throughout. I was recently changing the light switches in my bedroom and initially bought another brand, which was unfortunately more expensive and not as good in performance. After returning it, I came back to this one instead, as it has consistently proven to be the better choice.

Broke after 2 days and blew lightbulbs
Light was installed by a qualified electrician with 4 led spotlights and made constant buzzing noise, 2 days of back and forth emails with the supplier getting messages that were unclear & going in circles, at the end of day 2 the transmitter literally blew. It tripped all the lights in our house and we were unable to get them back on. We had to get an electrician to return at our cost & remove the switch entirely. It’s also broken one of our new bulbs, further cost to us. Supplier offered a replacement only and refused a return & refund, had to get Amazon to step in. Overall would never use or trust this company again and would not consider a replacement item. Very dangerous piece of kit.

Easy to use dimmer switch
I had to buy this dimmer switch after I changed the light on my lounge ceiling and found the bulbs were too bright. As the bulbs were dimmable it made sense to get a dimmer switch.. It is a lovely brushed steel which matches my other light switches.I'm disabled and in a wheelchair, I've limited hand dexterity and as I found the switch that was already on the wall easy to use I was wary of changing it.It was very easy to install, my brother in law swapped the switches in a matter of minutes.. My right hand is my dominant hand so I've to reverse into the lounge to switch the light on. I found this switch very easy to use. I have my light switches at a lower level than normal so i can reach them. With this dimmer switch I just push the button to switch it on then turn the knob to the right to brighten it, then turn it back to dim it. Then I push the knob to make sure the light is definitely off.I've found this switch to be good value for money, it's easy to use and I can have my light at just the right brightness nowIt has a good range of brightness, though I suppose it depends on what type of bulb you use. My bulbs are E27 and they cast a beautiful light over the ceiling when on full power.

Looks good and works well. Not the best quality.
Good:The dimmer looks smart and is easy to install using the instructions provided.Adjustment didn't take long using the adjustments screw on the back of the unit and allows the led lights I have to go very low.Bad:The rotary switch used to dim the light has alot of sideways movement and feels very cheap.The rear of the unit is very tight fitting into a standard light switch back box.The unit gives quite aloud buzzing noise when in use.The provided screws are far to long. The bottomed out in the back box with about 7-8 threads still showing and then started stripping their threads. I had to use the screws from my old light switch which now don't exactly match the faceplate.Overall it should do the job but I won't be buying again.

esteticamente....molto bello
Non ho ancora messo in funzione il pulsante, la valutazione che però posso anticipare riguarda la sua fattezza ed estetica.il materiale è di buona qualità, la satinatura lo rende bello al tatto e visivamente si caratterizza come un prodotto originale "stile retrò" come piace a me.sintesi: tornerò a commentarlo una volta che sarà operativo, per ora posso solo dire che è veramente bello.

PERFECTO si sabes que regula potencias de entre 60w y 400w máximo.
Esteticamente perfecto. Funcionalmente, si sabes leer sus especificaciones, también perfecto.Cómo bien indica su descripción, este interruptor regulable, regula potencias entre 60w y 400w. Tiene un regulador interno con el que poder jugar para ajustar más la potencia, en caso de que le conectes potencias inferiores, pero no está pensado para conectar una bombilla led individual.Normalmente las marcas informan mal sobre este dato, pero este no es el caso. Los que se quejan de que sus bombillas Led no se las regula, deberían mirar que potencia regula este interruptor (entre 60w y 400w) y que potencia tienen sus bombillas (si han cocentado 2 bombillas led, me temo que rondaran una potencia sobre 6/8w).Para esos casos hay reguladores que indican que regulan potencias entre 5w y 75w.Esas potencias que indica son las máximas, es decir, en mi caso he conectado una bombilla edison de 60w. He regulado el regulador interno al mínimo, y como se ve en el video, la regulación es PERFECTA. Puedo ir desde potencia máxima, hasta una potencia tan ínfima que sólo se ve el filamento rojo sin dar nada de luz, incluso si bajo más el regulador no tiene potencia ni para eso.Si buscas un regulador para bombillas led, y lo que tienes son varios focos Led (downlight) que en total suman unos 30w/40w, te hará un trabajo decente, si piensas conectar bombillas Led, que sumen en total menos de 25w, te hará un trabajo deficiente aunque seguramente quedes contento,y si lo piensas usar para una o 2 bombillas que sumen 4/6w, directamente no te regulará nada.Por cierto, si calculas esas potencias por lo que te diga la tienda, ten en cuenta que o la bombilla es de marca reconocida (philis, osram...), o todas las bombillas mienten. Yo tengo un medidor de potencia real de bombillas y las bombillas de aliexpress que compraba antes suelen tener la mitad de la potencia que anuncia el vendedor, lo aviso para el que quiera calcular que regulador necesita.
