Received quickly and works perfectly. Thank you very much

i have the model with neutral, the qr code says “not working” but in fact it works quite well.
the product is well built, good quality as i like it.

While the switch is a good idea in theory, the switch housing design is not so good. It does not fit a standard 3 gang US wall box, nor can it be flush mounted to a wall due to the location of the mounting screw holes on the baseplate. One of the description pictures shows the switch mounted on a wall, but that picture is backwards to the images showing just the switch (the image with the finger is reversed as well) which leads me to think it was a bad photoshop attempt. The screw mounting holes on the baseplate are directly inline with the switch’s component storage area. This will take a specialized wall box or some good behind the scenes mounting skills as I have not found a wall box online that will work yet. I would definitely purchase the switch, but maybe wait for a redesign or make sure you can get a wall box that will accommodate the switch before buying it as I did.

Works very well although I had requested the model without a screen

Good quality product, I will install still but superficially I have over voltage and under voltage protection. Works permanent in 220V, I like the product when install I come to leave an added feedback.
