I purchased this refurbished PC on Amazon and was extremely disappointed with the service and the PC. Let me say this first, the PC - for the speed and RAM, the price was basically right. There were options to select if I wanted to upgrade: example, add Microsoft Office for about $70, but I chose not to because I already have the software in my position. So, I purchased this item which supposed to come with Windows 10.The item was shipped under Amazon Prime and arrived three days later, which was pretty fast. Here's what happened when I received the item.The keyboard had a few keys missing - I found out they were somewhere inside the plastic bag; fell out, so I had to carefully replace them. The keyboard and the Mouse are of very low quality. But I was thrilled to have them. There was an instruction sheet in the box on how to activate the OS. To activate the OS, the instruction says -follow the instruction on the screen and, using the OS product number on the side of the PC, activate it. It should have been an an easy thing to do. However, when I turned the PC on, it says there was an error during the installation process and so "Click okay" to restart. When I did, it restarted over and over again but it didn't seem to go anywhere. I wrote to the seller but a note on Amazon states that it takes two days or more to get back to me. I didn't get any answer to my questions and tech-support request. So here's what I am going to say:*The PC is a good PC - it is fast more than 3 Ghtz, and RAM of 8GB is a very good computer for home use. If you purchased one of this and the OS wasn't installed properly, or was messed up during the installation process, follow this instruction: Install Win 7 or 8 if you have any of these OS and then upgrade it to Windows 10, which is free. I did that and it works perfectly fine.Another disappointment is the WiFi capability. The PC is listed as WiFi capable, but it doesn't.I don't recommend this seller!Thank you
