These animal repellent sensors are hard to assess whether they are working because sometimes there are very few birds around and therefore I assume they are working but other times the strobe light and high frequency sound that we cant hear anyway doesnt seems to deter them. I may need to play around with the frequencies that you can change at the turn of a button and experiment with different frequencies and see the results.
