Has anyone tried the pure green coffee beans extract for weight loss?

I just saw several advertisement on line about pure green coffee beans and how it is the new miracle pill for weight loss. It is suppose to keep your sugar from spiking and give you energy all day long without giving you the jitters. I’m curious if anyone on fluther has tried it and what were the results. Even if it doesn’t help with weight loss, it would be great if it boosts energy levels. I’m getting ready to move by next month and I could use all the energy I could get.
