Amazon.com: Arctic Air AWF25 Single Door Reach-in Freezer …

It had a lot of shelf space PLUS a lot of door space. During power outages (we get a lot!) it would hold temps below 20 degrees F for 72 hours with the door closed.. This new freezer holds temps between -8 to -3 degree F until the door is open or the power goes off. We have little shelf space (only 3) and no door space. Open the door – +10 degrees.
