I gather you're talking about that late-night show on Channel 4. It was OK that they showed the product I suppose, but I think anyone watching that would agree that they should really have given it more time.
Yes I would agree that they should have given it more time.I can't see the point of showing a product on TV unless it's properly explained. However, even if only 30 seconds was available, that time could still have been used better in my opinion and the product presented more effectively.
