The batteries were run down so i charged them for 4 hours before installation

The units have kept one annoying squirrel family away which is the main reason i bought this product

Posted by a reviewer on Amazon

The unit has no effect on single bird such as pigeon or magpie as i saw them taking a walk right in front of the unit without been motion detected

The reason could be the wind blow and branch movement occasionally set off the unit the combination of ultrasonic sound and flash light disturb the birds so they dont stay long on the lawn or come down as frequently as before

During windy nights i turned down the sensitivity settings because the units kept been triggered off and i was worried a plane or helicopter might land on our lawn

Hope these units will keep doing their jobs in autumn when squirrels and birds are desperate
