A great educational toy for young children. Unfortunately, if you are looking for a decent gyroscope for an adult this is not the right item. I knew that there was a risk of this being a cheapy but chose to try it out anyway. Both gyros are poorly balanced and thus many basic tricks wont work due to vibration. At high spin rates the gyros are very unstable and noisy. If you are old enough to appreciate quality pop a few extra bucks and get a precision gyroscope instead.
