What to know before buying

Listing details to confirm

The listed 5 A current rating and bulb-load claims of 600W incandescent/halogen and 300W CFL/MLV/ELV use different rating descriptions. Confirm the applicable load limits and bulb compatibility for the planned circuit before installation. The listing also gives conflicting voltage descriptions, including 120 volts_of_alternating_current and AC 100~125 V, 50/60 Hz, so verify the product’s electrical requirements. The listed 5.06 x 3.33 x 1.82 inches are presented as item dimensions, not a guaranteed wall-box clearance.

Who is it for?

A good fit for

People seeking automatic lighting in hallways, bedrooms, or restrooms, particularly where hands-free switching is useful.
Kasa users who want motion-triggered lighting with app, voice, schedule, and ambient-light options.
Installations with a neutral wire, a compatible load, and 2.4 GHz Wi-Fi.

Less suited to

Switch boxes without a neutral wire.
Installations that require 5 GHz-only Wi-Fi or a multi-way switching setup. The listing identifies this as single-pole and 1-way.

The supplied evidence contains aggregate star ratings but no customer-comment summary, so specific customer-reported strengths or complaints cannot be characterized. The rating distribution is mostly five-star, with a smaller but notable one-star share. That gives a broad, mixed satisfaction signal, but does not establish why customers rated it as they did or how reliably its motion, daylight, and app features perform.
