Definitely very good, although as Scott said, lowering tire pressure can be very important depending on the grain and depth of the sand. I've driven on beaches where you didn't even have to put it in 4LO, let alone lower the tire pressure. But I've also been places where the ruts were deep enough to require 10 lbs. per tire and 4LO to dig out and/or turn.

The other tip on running in the sand is to try to keep up momentum to stay on top of it. Slow down too much or stop and you'll sink.
