[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]: Honestly I havent noticed a difference and that is when I can keep it on my son. Hes 6 months old and smallest size is too big for his arm or ankle :(
[EX A]: negative

[EX Q]: I really liked the product and used it everyday. I liked the fact that it was portable and I traveled with it often. However, I purchased it in August and it did not last until the end of October.
[EX A]:
negative
