I have been buying these nibs for years and I couldn't be happier with them. They give me instant energy in a way that caffiene products can't match. No jitters - just pure usable energy. They work better for me in some kind of smoothie than just eating them plain, but they also work great by themselves. A little chewy and you get lots of brown bits stuck in between your teeth (a great look :> )but they still pump you up with energy.
