Replaced a still working freezer I had to defrost twice a year. This one fixed that. No frost in sight. Speaking of sight, really like the interior light and being able to see what's in there. The temperature monitor on the outside of the door is a big improvement, and the temp never varies. As for electricity, I've found no extra usage due to the frost-free operation. Also nice to be able to move the shelves. Glad I listened to my wife and won't miss the semi-annual defrosting ritual.
