great product - works fine
Looks very nice but installation is going to be hard since the requirement for the neutral line is somewhat unexpected.
Well, the installation went reasonably well after adding mains to the switch. Now the drawbacks: 1) the lamps are whinging at 7khz and 100hz peaks even at 100% brightness 2) you cannot set brightness with the timer of the app. I bought that dimmer because of that feature I saw on screenshots. That's a real disappointment.
