... I do hope it was a free App
Im 35 and can still hear them, the only way i found to sort the sound out was to avoid the supermarket!Definitely not illegal mores the pity, there is one at my local supermarket, very painful! I keep complaining but they won't get rid of it.. Even written to my local mp but no joy. Apparently nobody over 18 can hear them, but im 23 and have no problem. I can certainly see why the ultrasonic mouse repellers work!
