Query: Is it worth it?

I bought TWO (02) Bye Bye Birdie Wings and placed them on a relatively short balcony (10 meters long). After 3 weeks, the pidgeons were back. I tried moving the devices around, putting them in different locations, put the birds kept coming. I sometimes see the birds standing on the balcony railing, right on top of the 'Wings' !!My advise, don't waste your money & time.
