I have unfortunately purchased two of these computers, and both were not working in less than a year. I contacted the seller, and there was no response. They did respond initially when I first purchased the computer and it arrived with issues. I spent two days with customer service trying to get it to work, and they finally had me return it and sent me another. The second computer they sent worked great when I first got it, but died in less than a year. Before it died I purchased another one for my wife. It too worked well at first, but died within a year. From now on I will be purchasing new, as these refurbished computers seem to last only a short time relative to new.
