Hi Diego, today all manufacturers are in the same policy of planned obsoleteness if it lasts 5 years, be happy and if it reaches 10 good you can make a celebration. Buy a refrigerator that does not have a Chinese engine like Huayi or Motech and if it has an Embraco or Tecumseh brand, it would be good to take care of its doors with the weight of the bottles and that the gaskets do not stick together so as not to break them when pulling to open and place the automatic temperature in midpoint for life and care with products such as bleach bleach or floor perfumes with respect to the plate of the refrigerator. You can buy brands like Mabe- Whirlpool.Bosch.Columbia.Patrick.Sanyo.Samsung .. you can buy cyclics or with frost that is the same or No Frost that never does frost but when problems or failures appear it has more components to change and more expensive and labor also more expensive. I recommend national brands to the imported ones since after a while as always the spare parts disappear and I do not advise investing technology for their energy savings since in an arrangement all the savings went to trash greetings
