Review on SONOFF SNZB-03 ZigBee Motion Sensor: Wireless 🔦 Alerts and Light Trigger with SONOFF Zigbee Bridge by Noah Jess

Product comes with battery (and instructions include removing the insulating sheet for first use). Imagine my surprise when the product arrived without a battery. When you finally receive the battery, please note that this is indeed an uncommon coin. 2450 instead of the more common 2032 or 2016 cells. This battery is HUGE, which probably also means battery life is pretty poor. In addition, the product is simply "good". There are better switches from other manufacturers that are more tactile to use, easier to pair, more visually appealing and cost about $1 compared to the 01 series switches. I just want generic Zigbee devices, so I'll go Sonoff devices avoid in future.
