They work for a long time, after their "update" the computer began to work worse, i.e. slower. We replaced a good matrix with a bad one. (I gave away no vertical stripes, I got back vertical stripes appeared), the colors also changed. They also wanted to sell the old memory for the price of a new one. However, the money was still returned. In short, I don't recommend it.
I'm not happy with the service. Maybe this is my personal opinion, but even under the outwardly polite treatment from the staff, there is a considerable amount of superiority over the client: "We are VERY busy here, we have a lot more serious work, so if you want, we will indicate a place in the queue for you and within.... days we will try to carve out for you time...", this is what it looks like
