I initially received this computer and noticed it had 8gb of ram instead of 16gb so I rated it lower to get the attention of the seller. Eventually I was able to find a phone # for the seller (KT Renewed) and they made instant efforts to correct the mistake. I purchased 2 of the same computers about a year ago which is why I purchased 2 more for my business. For the price you can't beat it. A new computer with similar specs would cost $600+
