Product review (5 stars): Fast cooling
We live in Las Vegas so it is a must to have a fridge when we go on hikes. We used it going to Sedona, California and to Lake Powell this summer. We added an extra battery to the car so the fridge doesn't kill the car battery. The second battery gets charged whenever the first one is full. We had the fridge working for 3 days when we stayed in a hotel without fridge. We were  able to bring home goods from the farmers market without worrying about them going bad. It is quiet. You need to leave space to breath between the other items in the trunk and the vent.
