Bought two of these to scare off birds that are nesting in the eves of our home… I charged them 1st for 24 hours as suggested. I installed them close to the roof eves and the best thing I can say about them is the make great perches for the birds to sit on…:-0 Don’t waste your $$$'s, they Don’t work!
Bought one of these to scare off racoons in my yard. In the first week something pulled it out of the ground by the fourth week it was completely full of water from the rain. Total waste of $30.00
