The leveling feet broke off as soon as I tried to turn them to level the refrigerator. It seems to be a bad design. The plastic "feet" are connected to the shaft by spiral splines. The came right off with little torque applied. I ended up leveling the fridge with wooden blocks.
The refrigerator we previously had definitely needed an upgrade. This one was almost a perfect size, but a little larger than expected. Thankfully, we were able to sand down the shelf to make it fit perfectly. And it is in fact, a perfect fit! It works great, and has tons of room. Hopefully it will continue for many many years.
