Unaffected by the external environment. Easily adjust the sensor range and flush time with a screwdriver. Sensor range adjustment range: (0-8”). Flush time adjustment range: (1-6s).
EASY TO INSTALL & REPLACE BATTERIES: Simple installation taking most people less than 20 minutes. External battery design makes it easier to replace batteries.

RIMINDERS: The kit DOESN'T FIT ALL TOILET TYPES! Only fits with most flapper and canister toilets, not for dual-flush/ ballcock valve/ top-mount flush and pressure-assist toilets!
