“My son bought this for me to give to my 6 year old grandson. Thought I had better try it out first so I could show him. It's amazing very simple to do, but very effective. My husband.(my audience!) was very impressed. Grandson has t been given it yet, but I am pretty sure he will have no trouble astounding his friends and relations. I wonder if the reviews that say it doesn't work properly aren't using the ring at the right time?”
