RF-01OB Smart Radio Frequency Remote Deadbolt Lock - Oil Rubbed Bronze Finish - Keyless Entry for Home Security (Ideal for Front Doors, Back Doors & Vacation Homes)

I’ve had this lock for about 3 months, and already on my third set of fresh batteries. I’ve had other locks in the past which lasted about a year on one set of batteries (and with more use). Disappointed, because otherwise it’s a great lock.
