SONOFF S-MATE Extreme Switch Mate

Was a bit worried about fit since my wall boxes are the older 120 type, but this thing slots right in without any fuss. Rocker switch works perfectly with it, and the compact size means I didn't have to wrestle with extra wiring room. Exactly what I needed for a tidy install.

Finally, a switch adaptor that actually fits the weird 120 type box in my older apartment — the compact size made installation a breeze with no extra shimming. Works flawlessly with both my push and rocker switches, and I barely noticed it sitting behind the wall plate.

Took me a while to find something that'd fit my older 120-type mounting box, but this one slipped right in without any forcing. The rocker switch still clicks the same as before, which is exactly what I wanted.
