It took three months to evaluate.The product is really good.Firstly, it is slim and convenient, secondly, it is fast to start up, and the function of touch screen is also very practical.At the beginning, I felt that the keyboard was a little small and I couldn't adapt to typing.After using it for a while, I got used to it and used the old big computer, but I felt that the keyboard of the big computer was too big, hehe.
