## What reviewers say

**Lutron Caseta Diva Smart Dimmer Switch (DVRF-6L)** — One whitelisted tester — PCWorld/TechHive's Michael Brown — published a hands-on review of the Lutron Diva Smart Dimmer (DVRF-6L), calling it the smart dimmer to buy. He praises its understated paddle-and-slider design, no-neutral-wire install, and flicker-free dimming of a tested LED fixture, but flags the mandatory hardwired Caseta Smart Hub and Lutron's unclear Matter stance. No lab-measured numbers were published. (1 sourced review.)
