Bests & Worsts Reviews from Amazon

I decided to test the Packit before using it for work. I followed the product instructions. I put the bag in the freezer for 12 hours. Then the next day I put perishables (yogurt, milk, meat sandwich) in the bag and left it on my kitchen counter. I made sure my kitchen room temp stayed at 73 degrees, since that is the temp for most offices. After 8 hours I slipped a thermometer in the bag. Temp reading: 62.7 degrees. Then I pulled out my yogurt and stuck the thermometer in the yogurt. Temp reading: 57 degrees. So I went back to the website and reviewed their claim: "Built-in freezable gel keeps items cool for hours." But they don't specify how "cool" and for how many hours. How long had my yogurt been in the "danger zone" of 40-135 degrees? It went in the Packit at 35 degrees. More testing is needed. Maybe I didn't lay the food correctly in the bag (doubtful). Maybe I left a tiny whole in the zipper part (don't think so). I'm going to do another test, making sure the bag is zipped, making sure the food is laid in it as suggested, and then check on the food every two hours. I'm also going to do a new test: I'm going to refreeze the bag, take it out tomorrow morning, add my own ice packs (which is supposedly unnecessary since the bag has its own ice packs already built into its walls), and then put some new perishables in it. I will update you with the results. I am hoping that the Packit at least provides 10 hours of food safety with additional ice packs, because I really don't feel like returning it. Testing update: At 2 hour mark, my perishables were already at 47 degrees. So, they were already in the "danger zone" (and remember, you're not supposed to be in the "danger zone" for MORE THAN 2 hours). So I added extra ice packs and retested. At the 7 hour mark, the milk was 48 degrees and the yogurt was 53 degrees. This does not work for me. I have decided to just put extra ice packs in the Packit bag, then put the food in the bag, then freeze the whole bag overnight, and not open the bag AT ALL until lunch time. I guess this bag works for many others, based on the reviews. They are all still alive. But I am disappointed. I did one more test folks. I added extra ice packs and froze my perishables and the Packit lunch bag together for 12 hours. Then I took the Packit bag out of the freezer and let it sit on my counter for 6 hours. At the 6 hour mark, the turkey sandwich exterior temp was 39 degrees and the interior temp was 33 degrees. My lima beans and milk were 51 degrees. So there you have it. I'll just put extra ice packs in the Packit, pack only a sandwich, freeze the sandwich and Packit bag together for 12 hours, and enjoy my tiny lunch at work.
