I bought these glow sticks for my nieces (6 and 3 years). First: there are some reviews, is where grumbling about the wrong product description, it seieen yes actually only three or four colors. In fact, there are only four colors, as long as the lights are not started. However, the Starlights shine actually in the specified color range of 8 colors !! I think the lights very well, because they are so big and strong that I have to worry, what makes my little niece so. You can not Serber bend but do not have to be bad, there are bands supplied to the hang and hold real long. My info was that they, if they are in the evening bent in the evening of the following day still shine so clearly that the two still had fun with it, two days later I was surprised when 4 these glow sticks have the bedroom so strongly evident, I could patch up easily light the little after a very dramatic falling out of bed (the pavement had to after one minute again from, because everything was healed!). I'm excited!
