I bought a pair of these and one of them stopped working shortly after purchase. Since the other seemed to work well and was cheap, I bought another set. Within 2-3 months all 4 nunchaku will not work properly. The characters either move on their own or we get error messages saying they aren't properly connected, but they have 0 out of 4. Very frustrating. I think you get what you pay for but I will not buy Lyyes products again because the title describes the product.
