I installed the Tapo S500D in a single pole setup and it works well. Dimming is smooth and the white finish blends nicely with my wall plate. Setup through the app was straightforward, and I like being able to control the lights from my phone. It handles everyday use fine without any flicker so far. Just note it's a single pole switch, so it won't work for 3-way wiring. Good option if you want smart dimming without a lot of fuss.
