It puts a spring preload between spider gears in the stock open diff, thereby using that little friction to "couple" the gears together into a LSD. They make them in both "street" and "race" setups, the difference being the preload springs. On other cars they've given merely ok results with the race springs, the street setup is largely considered useless. Even with the race springs, their percentage slip is so small they're not much better than an open diff, and should only be used out of desperation on a budget or if no other alternative is available. The downside to the added preload is different wear patterns on the spiders and increased bearing face wear. We have plenty of options for our cars, I don't see any reason to choose theirs.

Don't waste your money. I know a lot of guys that tried it on their Hondas with minimal success. They DO work, but like Sam Lin says, they're not much better than an open diff.

I actually have tried that unit two years ago at the OTC. I cannot recommend it for any kind of powerful car. The friction is generated on the front and back faces of the planetary gears and there's just not enough surface area to create sufficient friction along with gradual slippage to be much good. I'm pretty sure you'll wear through your gears in less than 5000 miles.
