We stand behind our products! The Roost Smart Leak Detector has a 1-year limited warranty. The device is powered by AAA batteries (included). These batteries will typically last more than 3 years. Please note, the warranty does not apply to devices that are submerged in water as the detector is not waterproof. For more information please see Is the Roost leak detector waterproof?
