■ The catch — co-equal billing, always
It has no freeze sensor. The plain RCLIK is rain-only — in any climate that hits 32°F overnight, frozen sprinkler heads crack and cost more to replace than the sensor. It's the right pick only where it never freezes; cold-climate buyers need a combined rain/freeze unit instead.
Dealbreaker? Runner-up Orbit 57069N solves it — a wired rain+freeze sensor for ~$20. ↓

Not every controller takes one
Universal rain sensors need a 24 VAC controller with a normally-closed sensor input or a free common wire. Battery hose timers and many smart-only hubs (Rachio Smart Hose Timer, B-hyve faucet timers) have no sensor terminal — confirm yours does before buying.
Wireless range is a fantasy number
Stated 300–800 ft wireless ranges are line-of-sight ideals; brick, stucco, and metal roofs cut them to under 100 ft. Mount the receiver within 100 ft of the sensor regardless of the box claim.
It reacts, it doesn't forecast
Hygroscopic-disk sensors trigger only after enough rain accumulates — they can't skip watering the morning before a forecast storm. That pre-emptive skip is a smart controller's job, not a rain sensor's.
