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.

A: positive

Q: Had to return it several times for a close enough fit. A size XXX is actually a large adult size and medium fit around the arm/shoulder area. Finally gave up and got a full refund.

A: negative

Q: I looked long and hard to find a decent straw to use with my 40 oz and 30 oz tumblers. The Hiware 12 inch silicone straws are the perfect fit. The brushes that come with the package are a great bonus.

positive
