I bought two of these Dell Optiplex 9010 units from SKYTECH USA LLC  for average general home usage. I thought they were an excellent deal considering what the specifications are.Sadly, the first unit quit working after three weeks. It did not boot and gave flashing error codes/blinking amber power button indicating a problem. While frustrating, I knew I had purchased a renewed unit, and unforeseen problems can arise at any time. Please know and remember this in advance of purchase.In email contact with Skytech customer support, after a couple of emails back and forth helping me troubleshoot, it was discovered the power supply was defective. Skytech immediately shipped a replacement power supply. A few days later, I installed the replacement, and everything was functioning as originally specified.All that being said, if you get a good unit to begin with, it is an excellent experience and value for a home computer. The additional wifi and bluetooth peripherals included work flawlessly. If you are comfortable with the possibility of having to troubleshoot and replace a part, you can snag a bargain.At this point, the second Optiplex 9010 is an absolutely wonderful machine, and I cannot praise it enough. If you are not a gamer, not interested in Windows 11, and not requiring the absolute latest hardware, then purchasing this unit is suggested.For the record, this is the first time I have purchased anything refurbished except from the official Dell refurbished online store. While my experience with buying renewed here on Amazon was not without issues, I would purchase from SKYTECH USA LLC again. Their customer service stood behind their product and made things right.
