They are brilliant wow only closed my window and it went off oh dear twenty seconds it goes off for wow ideal for you blind people who have down stairs flats,Bungalows or houses but no good just for sake of it the police told me they only can have one if you have anti social behaviour in your road or streets Great I have to switcht it off if window cleaner comes i am turning mine on at night time when gone to bed I am going to sleep better now at night time horray now going to check my emails take care Love Carol x.x.x.x.
