All they are is caffeine and vitamins.
Studies have shown that caffeine has no beneficial effect on weight loss. You can't get enough caffeine through a pill to rev up your metabolism to make a difference.
Caffeine *might* suppress your appetite for a little bit, but eventually you become immune to the effect.
Caffeine *can* make your workouts more effective if taking about an hour before you hit the gym, but again, eventually you become immune to the effect as your body becomes adjusted to the stimulus.
Seriously. There is no magic pill. I've taken these, I've taken just about every diet pill on the market. They're all the same. For a while they'll give you a rush of energy, but there's nothing magical about them. It's caffeine and stimulants, plain and simple. And eventually your body will become accustomed to them and any "energy" benefit you might have gotten will be lost.
Big time waste of money, IMO.
