Both sources are from a single whitelisted outlet, Reviewed (USA Today), covering the Meross smart light switch (named 'MSS510', the HomeKit MSS510HK trim) across two smart-switch guides. The 2022 Apple HomeKit guide is hands-on tested; the 2023 guide is largely research-based per its editor's note. Neither published any lab measurement (response time, dB, or watts). Reviewers call it reliable, easy to install, and responsive across Alexa, Google Assistant, and Siri, while flagging budget build quality, a loud physical click, no app two-factor authentication, and an annoying on/off confirmation prompt. iMore, ShopSavvy and homekitnews were excluded as non-whitelisted. (2 sourced reviews, 1 lab-tested.)
Praised: Reliable and responsive to voice commands and remote/app control; Easy installation, helped by included wire-label sheet; Works with Alexa, Google Assistant, and Siri/HomeKit.
Flagged: Cheap / budget build quality, feels less premium than top picks; Loud physical click when the switch is pressed; Companion app lacks two-factor authentication.
