Ok from Grandads this working barking dog security alarm ,

Great item I have one myself , if I pop out I put mine in the window if any one comes near the house it starts barking ,


Please note these cost £80 ish new ,

Please see photos ,

“ Must Read , this works well But THERE IS SOMETHING LOOSE INSIDE , ( a screw ? ) so if shaken you can hear it rattle !
Does unscrew but I do not have the time. Hence only £20 wow
