I'm giving them a 4 start bc when I ordered it and went to set it up. I was missing a piece for the other screen to make it a dual screen. I waited a week to get in touch with them due to the holiday and couldn't leave a voicemail since it wasn't set up. I call after Christmas and they mailed out the part I was missing. I am now using both my screens and the computer I am super happy with it. Thank you!!!
