Review on Light Up Your Party: 25 Pack Of Waterproof Glow Sticks For Kids And Adults - Perfect Party Favors And Decorations by Megan Smith

These are advertised as "Industrial" grade. They a FAR from that. First one was bad right out of the box (already snapped?). There is no way to tell some of the colors apart without activating them, they glow for maybe 2 hours at a mediocre level, then fade out completely over the next 1 or 2 hrs. I use Industrial grade glow sticks at night for training. These do NOT give off enough light for that. I have actual industrial grade glow sticks, and will upload my side by side video comparison soon, including a time lapse of the 2 brands. I know the description also says party favors, but using the term industrial grade is misleading. It implies dual use, which is absolutely not the case. And now I have to repackage them and go to UPS to get a return.
