Does the Ab Rocket Really Work?

If you watch any sort of commercial television, you've probably stumbled upon an infomercial for a device called the Ab Rocket. In the infomercial they show you a bunch of very good looking men and women who swear by the AbRocket and claim that it's the reason they got their flat and sexy stomach.
But does the Ab Rocket really work or is it a scam? I haven't used this machine, and I want to make that clear, so I have no idea whether it works or not. However, I just don't see how it can do all that it's supposed to because it only takes care of one aspect of the process which is necessary to get a flat stomach: the exercise part.
The other aspect is the nutritional one. Simply put, you can't lose belly fat is your nutrition is bad, and I don't care how great the workouts which the Abs Rocket provides. The truth is that it's well known that you can't spot reduce fat. This means that if you just work your abs, which is all this machine does, you still burn fat proportionally from all over your body. You may develop the stomach muscles, but you won't be able to burn that stubborn layer of belly fat which covers them up.
Therefore, it is my opinion that the Ab Rocket, or any other abs workout machine, won't be enough to give you the kind of abs you truly desire. To do that, you need to workout right and most of all follow a sound nutrition plan.
If you want to workout with this machine then by all means do so. If it gives you motivation to exercise then it's worth it. But, make sure to learn how and what you need to eat in order to really get to the core of the problem which is the excess belly fat that you're carrying.
