Booby Track
An unusual shape, a textured ball and additional corner rollers.
The cheekiest adult-themed mouse I know.
They suggest using it to spice up work meetings and dull spreadsheet work. The rest of the box copy is wonderful too.
It's nice that they put thought into not just the shape, but the material and colour of the ball's coating as well.
A notable construction detail is the additional stabilising rollers at all four corners. Apparently testing showed the mechanism needed reinforcement ^_^
