[EX Q]: Look out. I’ve used these for several years and the colors are no longer red, dark blue, yellow and dark purple. I received neon green, orange, aqua blue and fuchsia pink. Dark purple was okay for my little guy, but bright pink isn’t going to work. Will either have to use one old car from last school year or order another set to have four. I put two under a yumbox and two on top in a lunchbox. Others are right about not staying cold long, but works great to keep non perishable items cold.
[EX A]: positive

[EX Q]: These bracelets work fantastic. I can't see mosquitos around me while i wear them. So great experience for me as a terrible mosquito magnet. Thanks. I would buy again.
[EX A]: positive

[EX Q]: Ordered 2 signs for Christmas. they charged me for 2 and shipped 1. Thought I was done Christmas shopping but now I have to head out in the winter weather at the last minute to find a gift. Then I'll have to try and get my money back from this company.
