As someone who has been using the entire Aimcise line, I have to say I love the new product READY. As it combined 3 of the products I was previously using, it has made it more convenient to use the line as there are less to take, but especially when I travel as I have less to pack! Also, this product is even more effective! I am not a coffee or energy drink taker, but notice I am more alert and focused for longer when I take READY than when I don't, and even when compared to the previous system! There is no "crash" and as a competitive archer I can safely take this with no worries! READY for the win!
