what special fridge?

Your Elba hood was most likely manufactured by a factory in China using components that would most likely be found in a Midea hood.
They started out by making a very good kitchen hood, in their early years it was the most effective and powerful as it was designed mainly for a Chinese kitchen. They did a good job but the build quality of their early hoods were not the best and they were certainly very noisy especially after a few months. It was however relatively affordable for a good kitchen hood. My aunt still has one of their first few that was sold here and is now 18 years old, still works as it did despite being mounted in a wet kitchen.

Today their hoods are good because their high end one is less expensive than a Bosch, Teka or Electrolux, has better suction power and effectiveness,  lower power consumption and if you follow their ducting specification it would be one of the most quiet hoods you have heard, the secret to its effectiveness is a very powerful DC motor which they are a pioneer in.
They are most well known for their kitchen hoods but now their ovens and microwave ovens are good too, not cheap mind.
Depends on what you can afford. Many are good but most likely you would not be able to afford them.

Why teka and electrolux not good????
