Bests & Worsts Reviews from Amazon

These 'Cool It' ice packs are designed similar to the Rubbermaid Blue Ice Block but are better sized for insulated lunch bags or lunch totes. DESIGN: Individual ice pack is approx 5" square and about ¾" thick, so it fits well in those smaller insulated lunch bags/lunch totes or personal coolers. Each ice pack has a small 'donut hole' in the centre of the square so the frozen ice pack can circulate the cold air freely in the lunch bag/lunch tote. WHAT I LIKE MOST ABOUT THESE 'COOL IT' ICE PACKS? They are made of antimicrobial hard plastic with the non toxic blue gooey stuff safely on the inside ... unlike Blue Ice Bags which works fine but puncture over time - especially in kids lunch totes :)) I freeze the ice packs overnight. Usually, two ice packs are enough for my lunch box - one for my soda and, another for my cold sandwich or fruit salad. The ice packs are designed to use with the Fit & Fresh Lunch on the Go container. However, I simply place one of the 'Cool It' ice packs underneath my Food Container - it works great! CON: These 'Cool It' ice packs are not sweat-free. As the ice packs melt, they do sweat a little in my lunch box. I don't find this a problem, but I have a quick fix nevertheless! TIP: To make these re-freezable ice packs sweat-free, simply wrap individual ice packs in a sheet of paper towel before placing in the luch tote. Bounty paper towel works fine ... and of course, it's re-usable! Hope my review was helpful ... Jeffrey A. (Jeff) DECEMBER 2016 UPDATE: I've been using these ice packs almost every day for the last four years and they look as good as new. I like knowing that these ice packs not only looks clean but with the antimicrobial plastic I feel safe with them underneath my food containers ... Jeffrey A. (Jeff)
