Best thing I bought
I love this product, I've already had this product for a year for school lunches. They've survived school and little clumsy hands. I decided to buy more to use within the home. I have saved such much money and no longer buy poppers. My kids love them, they are easy to clean and maintain. You can purchase replacement kits for them as well as ice box gel packs that they fit into to keep them extra cold in the hot summer. I high recommend this product.
