Love this little gadget. I love to make the ice balls with a a wedge of lemon, or a sprig of parsley. They are a perfect addition to any pitcher, and great conversation piece. I am going to use these in the winter for a "ice ball hunt" when there is snow outside! Makes a great gift too!

Does PQQ help with MEMORY PROBLEMS? I purchased it because I read an article that says it does help memory issues. Not one review on here has mentioned any of the sort. Please advise. Thanks
