Query: Excellent Product

If you are trying to learn relaxation through biofeedback, this is the product to buy. Packaging, support, presentation, and hardware/software quality are the best that I have seen. No down side. It's not a game in the usual sense. More of a way to learn techniques in a quiet and amusing way.There is room for a little mischief. Instead of allowing the balloons to flow smoothly, I tried busting a few. Type A personality shows through occasionally. I will be purchasing the next item in the series. I am learning to relax, at will, which will be helpful in my high-stress occupation. Good luck.
