I like the term "Nevercold", I hope we do not have problems with the one we were just forced to order due to dimensions of the opening! My "Nevercold" on my last boat was still working strong after 22 years, but they were made in the USA then. A good replacement if you have the room is the Vitrifrigo, it is the "Tundra" under another name. Wonderful warranty, service record and according to local service dealers, a joy to service and to deal with the company. They are also larger than most as they used a different material that was not as thick.We did not have the room for it, but it was our first choice.
