I picked up the Tapo S500D 4-pack to replace my old dimmers, and the difference is clear. The single pole setup was straightforward and the white finish blends nicely with my wall plates. Dimming feels smooth without any flicker on my LED bulbs, which was my main worry. Having four switches let me upgrade several rooms at once. I do wish the description had listed more specs, but based on what I've used so far, it works exactly as expected. Solid choice if you want smart dimming in multiple spots.
