If you can afford it, get Miele or specifically the Bosch models that are made in Germany (many lower-end Bosch models are contracted out to e.g. Turkey, and not quite as good).

> Miele have unfortunately changed their sales policy in UK and Europe.
> This applies to all online spare parts retailers including Miele directly.
> Most Genuine spare parts are now only to be available to repair engineers and not directly to the public.

Our fridge however is Japanese Panasonic. Not a common choice in Europe but it’s been great so far. Zero maintenance. No frost. Has some minimal digital control but we don’t touch it. YMMV.
