I ordered this for an 'off the wall' use. I want to scare foxes from the garden and recorded 20 seconds of ferocious lion roaring ...... very scary ......I sealed it in a clear plastic bag and that kept it fully waterproof through a week of driving rain BUT sadly the foxes didn’t give off enough heat to activate it. I have nightcam footage of foxes walking right up to it and sniffing it but no response from the device. If I walk within 20 feet of it I get the full roaring lion so it works 100% for it's designed use. A nice piece of kit but not for scaring foxes.
