Flat Abs Without Crunches

So you know I'm a big fan of the Crunchless Abs program. It's the smartest workout series I've ever tried. Crunchless Abs demonstrates workouts for real people - starting from the ground up and getting more advanced as you get stronger. It really pushes you toward flat abs in a supportive way and without crunches. But I just ran across this new product, also from Linda LaRue: Core Transformer. Do you know what it is? I haven't clicked around yet. It looks like a fancy resistance band type of tool - have you tried it?
