    Fun to build but that's about it

    Overall: 3 out of 5

    If the Yes or no was truly random, I would be having fun with it but instead, it is a timed slowdown to a stop that occurs the same way every time. You hold the button down, it cycles at a speed until you let go and then it slows to a stop on the yes or no, exactly the same way every time. So.. if you let go at the same point every time, you will always get the same answer. So in order to use it without bias, you need to not look at it while you hold and let go of the button. takes the fun out of it. But I did like building it. For the cheap price, it gave my Son and I something to do together, what other value it has now to me, I don't know.
