The best smart sprinkler for small to medium-sized lawns, or a small portion of a bigger yard. Each device reaches from approximately 2 to 30 feet* for approximately 2,800 square feet of coverage. Box Includes: (1x) OtO unit  (1x) Mounting bracket  (1x) Wall plug and 50 ft. outdoor cable (for shady yards or power boost as needed) *NOTE: Many factors can influence OtO's max reach. We highly recommend a hose-end flow rate of at least 5.6 gallons per minute (GPM) in order to reach 30 feet.
