Strayt Touchless Bathroom Sink Faucet with Kinesis Sensor Technology and Mixer, Dc-powered K-104S37-SANA-CP

After 1 month of service in a master bath used by 1 person, the AamA batteries were exhausted. Cumbersome process to access and replace the batteries. The website says this faucet will run approx. 4 yrs. on the batteries but if they require replacement in 4 weeks ( less with more family members). The screw top plastic battery cartridge will never hold up. Second faucet was just placed by the remodeling contractor. It has a steady drip. No help online or in the accompanying literature.
