Best Mini Fridge Review no. 3. Avalon By Keyton A1-31CFDDBLK Refrigerator And Freezer With Double Doors. This unit is an inch taller than the Haier, at 35 inches high, so whether you’d still call it a “mini” fridge is up to you. We call it a terrific small refrigerator/freezer (if you have room for it) and worth the #3 ranking on our best mini fridge top 5 list.
