I am so happy with my refurbished Dell tower. It replaced my chugging 11 year old relic E-machine Vista. It arrived 4 days after ordering, packed well and included a new keyboard and mouse, which was not expected at all. I did not receive instructions as some have, but even me, "old school" was able to put it side by side with the aging tower and figure out what went where!  I was not able to use my original keyboard, as the portal thingy/ plug was not supported on new unit, so I was so happy they sent one. I did get the packing slip and a paper from Microsoft with product code and instructions. Love the Win10 and Dell, it is lightning fast, and has tons of pre installed things I will never use but I love everything about it and highly recommend buying it! I am retired and very budgeted income so this was the best way to upgrade for me. I only use my desktop for buying, selling, music and emails so I didn't want to spend a lot of money. My printer works with it, never missed a step I am back in business!  I also purchased 3yr warranty. I did have a question I couldn't find poking around, and emailed first night I had it and in the morning I received a reply! I hope this helps in your decision making, I know the reviews helped me decide so I wanted to share my experience. enjoy each day : )
