Annoy-a-tron is jokes.
Ages ago, and I'm gutted I never picked up a few because I checked since and not seen them, my local tesco garage had similar devices which were only a quid each. Bargain.
Each only done one sfx, they had mosquito and dripping-tap.
These ones were tiny though, keyring sized and were light activated.
You stash it, when your target goes to bed or whatever and turns the lights out it starts a minute from then... soon as they come back down into the room to check out the noise they inevitably turn the light on and it stops making the e'er noise.
A great little practical joke I thought
