I ordered the product knowing that this was a second hand desktop, however they stated being authorized by Microsoft to refurbish these desktops. I received the package initially on time. I stater putting all the pieces together and the monitor bases had some missing pieces I contacted the costumer service they say will send me the pieces that I needed. The problem was when I started the CPU, it never started I called the costumer service again they asked me to open the CPU disconnect and connect some cable and it did not work, they decided to send me a new CPU, which means one more week without having a functional desktop which delay all the work you have. Additionally, cosmetically it seems to be really bad, I know it is a used product but there are several deep scratches and the cleaning of the keyboard and screens it is definitively not the best, or at least not what is described in the description of the product. DON'T WASTE YOUR MONEY AND TIME.
