I purchased 2 of the Birds Away Attack Spiders during the summer of 2005. I applied each of them and they did an excellent job of deterring the woodpeckers. Sadly though, I did not locate the product until there had been considerable damage done to the wood work on my house. I am happy to have a product that activates when it is needed and therefore sustaining battery life. If there is anything else I can do to be of assistance please let me know. The service in which you provided me in follow up is beyond high level service most people ever experience. You have earned a Happy Customer and beyond that I will sing the praises of the product you so highly represented.
