Title: A piece of junk
Review: This sounded like a good idea, but the implementation completely negates any actual usefulness. It was designed and built by those who have no real knowledge of gyroscopes and how to built one. As constructed, the only exercise will be trying to get it function well enough to out perform a one pound dumbbell which is one tenth the cost. I purchased a child's toy gyroscope several years ago that still generates much higher gyroscopic forces with far greater ease of operation that this thing.I gave it one star because that is the minimum allowed.
Is the review positive or negative?
