Don’t know if by high efficiency they also mean flat bed instead of standing freezers. Especially in -80 you can tell easily how big a difference that makes. The moment you open a standing -80 you can see the frozen air fall out and down. It then runs for hours to cool back down. We had a flat bed and that bigger won’t even switch on unless you keep it open for minutes straight.
