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

Parents to three small children, Lisa and Luke were conscious of their family’s carbon footprint, so when their eldest son was made an ‘eco-warrior’ at primary school, they wanted to do their bit. Researching sustainable materials, they hit upon using recycled rice husks to make biodegradable lunch boxes. Former archaeologist Joe loved nothing more than a freshly ground cup of coffee in the morning, but what he didn’t love was digging out the mushy grains from his cafetiere afterwards. So Joe came up with an accessory that scoops up the grounds with a simple twist. And too many wet school runs led Lottie to invent an all-in-one waterproof for children with no need to remove shoes, a hood which fits over helmets and hidden magnets for quick fastening.

Once all three inventors have watched the customer responses and given their own thoughts on the feedback, Lucy reveals who has won the coveted The Customer Is Always Right winner’s trophy. Show less
