Negative Positive
Title: Useless
Review: For such high price I thought it would be an effective solution to solve the bird problem we have in the building. However, it is useless. All birds are not affected by this machine at all. It even worse than other cheaper stuff I pruchashed for this problem earlier. Other cheaper similar products at least were effective for several days. This one is not working for any one minute!
