This Digital Video Memo, sticks magnetically to the fridge door and provides record and store memo functionality for communicating with busy family members. You get 30 seconds of video per recording, and the 1.5 inch LED screen is surprisingly usable. Just press a button to start recording, and another to playback.

Two things make it less than ideal. First you can only store one message at a time (subsequent messages overwrite the first) and further, the thing has an auto shut off to save (USB rechargeable) battery life, which means you have to push to power it on before recording, which could be a button too many for some people. But hey, it’s £29.99, so who’s going to quibble?
