Initially, I gave this vendor high praise for quick responses to my questions and even after delayed delivery, I was happy to give the computer a try. Now about six months into using this computer, I can testify that it is junk and DO NOT buy if you need a reliable computer. It started with the computer slowing down to a crawl after installation of few applications and downloading a couple of big datasets. Then it started overheating, and the fan running overtime. Now, it is painfully slow, the fan is annoyingly on every minute(even after trying to clean possible dust clogging), I have done everything I would think to fix the issue but they persist. I called and left a message with the vendor back in January and never heard back. I wrote again, through Amazon in January about the issues, they wrote back that they will get someone to help me. More than three months later, I am still waiting.  Bottom line, for the amount of money, you can get a decent computer that is reliable and durable, not this junk.
