Dyson’s most overengineered gadget may have a waterproofing problem

Dyson admits a component issue but won't say what's failing in its $500 toothbrush.

The short version

• Dyson admits a component issue but won’t say what’s failing in its $500 toothbrush.
• There’s always a danger in over-complicating products.
• The apocryphal story of NASA spending millions crafting a space pen while Soviet cosmonauts used a pencil is often cited as a prime example, even if it’s actually not true .

What happened

Perhaps it’s not surprising that Dyson has got into hot water trying to reinvent the electric toothbrush . The Chinese invented the first bristle toothbrush during the Ming dynasty.

Why it matters

That concept muddled along quite nicely until 1937, when Tomlinson Moseley filed a patent for the earliest electric toothbrush.
