My kids loved putting these together, and it worked well because I was able to split them up between the two kids, so they could both play. My son linked them all together to make train tracks that he could see in the dark.
My daughter stuck them in my hair, and made me turn out the lights, so she could play alien! They had a ton of fun with them, and for the price, they aren’t that bad of an investment.
My set did have about 20 of them that were duds, and they didn’t last but maybe 4-5 hours, but in that time the kids enjoyed themselves. I think they will be perfect for next year, when we go to the fireworks display, and since I can get these Glow Stick Bracelets on Amazon for $8.99 + $4.49 shipping, they are a much better deal!
