We all know that Samsung is a brand and it is competitive with all the products brand. Coming to Samsung double door refrigeration it's working is amazing because I am using that product since from 4-5 years.Till know there is no problem with that. But according to my view some though it is a brand some changes must be done, according to the things kept in the fridge it should automatically set cool according to that product.but any way this is the best one, althrough every product is good but experiencing the product plays a crucial role.
