We needed to replace the large 30+ year-old Zanussi freezer that we kept in the shed which has given great service in that time, but was probably no where near as efficient as today's models. This is smaller (small enough to fit in our store-room in the house) but perfect for us 2 as the chldren have now left home. Having now had it several months, I can report that it maintains a good -18 to -20 centigrade on the normal setting, while at the same time reducing our electricity bills by about 15-20%. Should have done it years ago!
A Vacuum Release Valve prevents the creation of a vacuum inside this chest freezer, so opening the lid is easy every time.
