No, it won't give you great abs. It will burn a few calories, sure. Probably make your ab muscles stronger. Getting great abs will largely be the result of losing fat through eating well.
I think all machines work, but why buy it when you could of just done regular ab workouts that require just a mat and can be done at home like sit ups, crunches, bicycles, etc.
