They seem to make so much stuff that I'm willing to bet they don't even know what they make. Cheap Chinese rubbish
You brought me 15 years back in time with this "Cheap Chinese Rubbish".
But, you are not completely wrong.
Cheap? Yes.
Rubbish? No.
For the first time this year, Xiaomi is the biggest phone maker company in terms of number of devices sold.
I like their philosophy for not spending too much money on marketing or retail stores.
Instead invest the money on R&D and quality of the products.
It has paid in the mid term. They are a relatively new company compared to the likes of Apple, Samsung or even Huawei, but leading the way.
Now, TVs are a different game than phones.
But, I would wait before give a negative opinion about a product from Xiaomi as I have used in the past different types of products from them (phones, led lights, electric scooter etc.) and I must say that I have been very pleased with the quality and durability of those products.
I, also bought a 500€, 55", LED TV (Xiaomi MI 4s) for my parents, and, though it's not a tv for me (it's a LED), I would say that it is more than acceptable for the price.
Especially the user interface is very fluid compared to my old 65EF950V from LG that I paid about 4500€ back in 2016. Why I am saying that? Often my TV restarts to "free up some memory" and the user interface is so slow that I have learned the sequence of key presses by hart and just execute them and wait for actions to happen.
I would expected that a better processor and more RAM and storage should have been included in my high end TV. This what XIAOMI normally does, like in the 77" version announced: 8.5GB RAM and 64GB internal storage, and all the features you'd expect from an high end TV, and half the price.
In paper this is a winner, but, of course, I would expect a full review here if this would be possible.
