The first computer I ordered stopped working after my second use with a beep sound going off 4 times every time I tried turning the computer on. I was going to get a refund, but the company suggested sending another one. So, I shipped the not working computer back to the seller and they sent me another computer. That computer worked fine for a week or so, but it eventually stopped working again. We wanted to use this computer to perform data analysis in a small business environment, and this situation caused us a lot of delays and money loss. If you need a reliable computer and do not have to worry about returning it after a week of use, you should stay away from this. I was lucky such that both computers died within the first month, so I was able to get my money back.
