3 Telltale Signs Of A Bad Concept

The internet is oozing with product concepts, but our brains flag many of them as "bad" at first sight.

What is it that pushes a concept into the "bad" category?

2- Unnecessary. The concept solves a problem that doesn’t matter all that much.

3- Faulty. It doesn't appear that the concept would function properly.
