I bought one in October 2018 . The laptop worked two months and was switched off completely. I took it to the service and they exchange it with new one, as the failure was original and not because of me.
The new one I used 3 months and another problem appeared: laptop touchpad stopped to work. BTW, I noticed the problem after using the laptop one week. I took it to the store to return, unfortunately, this time they didn't agree to exchange it with a model of another brand, cause I will never trust this product and company anymore.
So my comment is the following: Xiaomi products are a completely failure. They surely failed trying to replicate one of the most popular and qualified brands(Apple). Lying customers and selling them a product with such a poor quality and with a high price compared to other laptops, is an awful step. I am so disappointed and I regret that I bought Xiaomi product. And I hope I can tell as many people as possible about the awful quality of Xiaomi products preventing them falling into the trap like me.
They should Just stop lying people!
