Lucy Alexander is joined by three inventors to watch footage of customers as they unbox, test, review and score their precious products.

Aware he was being a neighbourhood menace with his noisy, banging bin lids, electrician Scott has come up with a gadget that clamps on to the back of a wheelie bin to prevent the lid going bump in the night.
