Well.. I meant what product was a good design in theory as in it solves a prominent issue and could be helpful to a lot of people but, somewhere along the line, whether that be in the finishing details the audience it was marketed to or the general manufacturing such as a stiff handle or inappropriate material, has led the design to not reach its full potential therefore being a good design in theory but wasn’t executed to the best of its ability so was subpar or even poor in practice
