CrowAway total wast of money and time.
Bought this cd and gave it every chance over a 3 week trial. Used it in every direction and in different locations with several players from 2 watt speaker's to 10 watt speaker's at different sound levels and from ground level as well as roof level. Crows took absolutely no notice of the sounds at all dident even cause a flutter, at one time they were preening themselves while listening to the CD. I was determined to give it every chance as none of us want to feel we have been a mug but that's what's it has done. It is an absolute wast of money and time. It doesn't work, not even a little bit. We have crows nesting in the trees all around the farm and Jackdaw's nesting in the stable roof, magpies in the garden and none of them, not one took any notice of the sounds on the CD, dident make any reaction to it at all. I really wanted it to work and gave it every chance but it's of no use whatsoever, you will get more reaction hanging the CD on a bit of string and frightening them for a while as the sun makes it glint in the breeze. I feel completely conned that I fell for this and spent much more buying portable CD players to play it on. DON'T WASTE YOUR MONEY, IT DOSENT WORK!!!!!!
