Bests & Worsts Reviews from Amazon

horrible had it in the freezer for about 13-14 hours. left for work at 5am for work. first break was about 8am the ice pack already lost a lot of its cool. 10am lunch the pack was barely cooler than the temperature of the office. 1230 2nd break the ice pack was already room temperature. when i got off work at 230 it was warm. i was planning on buying a couple of these since i go camping a lot through the summer or when i go fishing to save room in the cooler but i wouldn't trust these for more than 8 hrs out of the freezer. for this price i shoulda just got like a walmart no name brand or something.
