Bests & Worsts Reviews from Amazon

I came across these by accident. I don't have any Fit & Fresh containers so I can't tell you about how well they work with those but I do pack lunches for my 3 kids. I like these because they're thin. I can put one on the bottom of a lunch box (we have soft-sided ones from Lands' End) and put a milk box, sandwich, and fruit cup on top of it. Previously I'd have to figure out how to wedge one of those blue bricks in between all the items that needed to stay cold. These are made out of hard plastic so they stay flat of course...I'd tried the soft ice packs but I could never get all 3 to freeze perfectly flat each time. The kids tell me their lunches are still cold at lunchtime so the ice packs are working. The ice packs only have to keep cool 3-4 hours at most anyway. If you're packing lunches for your kids and tired of the bulky blue bricks, get these. They work so much better. Update Dec 2015: These ice packs are still going strong. In fact, I came back to order more to replace leaking ice packs from another company (http://amzn.com/B00OH5IVQ4). I use these daily in my lunch box too...never had any problem with them. The other ice packs didn't even last a year.
