Rayzeek RZ022 壁掛式動作感應器，歐盟標準

Perfect score for this motion sensor switch! What impressed me most is its exceptional energy efficiency. After installation, I specifically monitored my electricity meter – places like hallways and storage rooms where lights used to be left on are now fully automated: "Lights on when you enter, off when you leave." It completely eliminates wasted energy from forgotten lights! The manufacturer’s claim about ultra-low standby power is absolutely true – I’ve seen a noticeable difference in my electricity bills over the past few months!

Motion sensitivity is perfectly calibrated. I tested it multiple times: whether in bright daylight or dim nighttime conditions, it accurately detects movement with quick, delay-free response. Installation was straightforward too – just replace your old switch (make sure your wiring is compatible).

Beyond saving energy, the convenience upgrade is massive! No more fumbling for switches during nighttime bathroom trips. When my hands are full, the lights turn on automatically – total game-changer! For families with kids or elderly members, or anyone pursuing a smart, energy-efficient lifestyle, this sensor switch is absolutely worth the investment. Highly recommended!
