I bought this refurbished computer from Amazon which I have never really had any problems buying from Amazon. It’s a Dell latitudes and it lasted me seven months. I can only use it for about 30 minutes the screen glitches and then it shuts down for a period of time. I have done some troubleshooting on my own and I’m left with only contacting Dell which I’m going to then pay to have it fixed. My advice is buy new or if you’re buying used buy from a walk-in store like Best Buy
