Small and simple to connect, they can fit in the junction box behind the switch. Can forward / bakkantsdimring. have synced up against my ZNet little v2 without problems.
Tip: use tretrådsinkopling. First I tested with two-wire a few where there were three forward stroke. This worked so-so on the LED display, the load was well too low. There, I drew up an extra leader until the neutral, then it worked fine.
The only negative is that they only manage 250w, running is not LED, it can be a problem in large chandeliers.
