SawStop reacts in, what? 3 ms?

They claim 5.

Versus 117ms for the Whirlwind. And you can both use the blade again
and start the saw back up 1 second after the E-stop.

If something slips, your hand can move a *long* way in 117 ms. Remember that
the Whirlwind mechanism won't engage until your hand is *right there* at the
guard -- IOW, when your hand is only inches away from the blade. And moving.
Moving *quickly*.

No thanks.

I agree that Whirlwind is clearly better than no protection at all. But better
than SawStop? No way.

If the Whirlwind ever comes to market, who's to say it couldn't also be
installed on a SawStop? Breach the Whirlwind's safety zone and the saw begins
the less drastic one-second shutdown, without damage to the hardware; touch the
blade and BOOM. Best of both worlds.
