Square Hole Saws For Drywall - Worth The Price?

Kickstarter project: Square hole saw, looks like a US version of the UK Quadsaw.

Demo:

The Quadsaw is preorder for ~$250, no price yet for the square hole saw kickstarter.

These seem like good time-savers, but are they worth it for the price? How many installers here routinely cut holes in drywall for old work boxes?
