This is my first 20 cu ft  class chest freezer. The height is lower than the 15 ft units making it easier to reach bottom. It replaced a dying 18 yr old chest, I pleased at how quickly it reached and maintained zero degrees. I miss the alarm feature common to many smaller freezers. I guess that's a more competitive market. My old freezer's alarm saved me hundreds of dollars so I'm looking for one to add to this unit. If you have the space for a freezer this big, you will enjoy the extra capacity.
