THESE BELL AND HOWELL SOLAR PIR MOTION ACTIVATED ANIMAL RPELLER (TRADE NAME FOR VAN HAUSER LLC, ARE ADVERTISED ON TV AS "NO BATTERIES REQUIRED" BUT WHEN I RECEIVED THE ANIMAL REPELLER, THE THE INSTRUCTIONS ARE THAT THEY DO HAVE RECHARGEABLE BATTERIES, AND THERE IS A SWITCH THAT CAN BE MOVED SO ONE CAN REMOVE THE RECHARGEABLE BATTERIES AND REPLACE WITH ALKALINE BATTERIES.
SINCE THE REPELLER IS SUPPOSED TO PRODUCE A SOUND THAT ONLY ANIMALS CAN HEAR IF THEY ARE WITHIN 30 FEET OF THE UNIT, I DO NOT BELIEVE IT DETERS ANY MOVEMENT AT ALL. WHILE IN MY HOME, AND AFTER BEING OUTSIDE FOR THE SUNLIGHT TO CHARGE THE BATTERIES, I SCRATCHED THE GROUND IMMEDIATELY IN FRONT OF THE UNIT, A RED LIGHT WAS SUPPOSED TO COME ON AND THE UNIT WAS SUPPOSED TO PRODUCE A SOULD THAT ONLY AN ANIMAL COULD HEAR, NO RED LIGHT CAME ON IN THE UNIT. I ALSO REPLACED ALKALINE BATTERIES, AND STILL NOTHING HAPPEN.
NOW, I HAVE SENT ONE UNIT BACK AND ASK FOR A REFUND, WHICH THEY CREDITED MY CC. BUT THEY DID NOT REFUND THE $6.95 S&H, THE COST OF RETURNING THE UNIT WAS OVER 2usd to mail back. I BELIEVE THAT COMPANIES THAT SELL DEFECTIVE PRODUCTS MAKE ENOUGH ON THE SHIPPING AND HANDLING THT THEY STILL MAKE A PROFIT AFTER ALL, THE PRODUCT WAS MADE IN CHINA AND THEY PROBABLY ONLY PAID A DOLLAR OR TWO TO HAVE THE FALSLY ADVERTISED ANIMAL REPELLER MANIFACTURED AND SHIPPED TO THIS COMPANY (VANHOUSER LLC) IN NEW YORK.
