From my point of view they gave the impression that they were an authorized Dell refurbisher.  I understood that the seller only at a 90 day guarantee but authorized Dell refurbishers meeting Dell standards Dell provides a one-year warranty on parts. This is industry standard and obviously these guys don't operate by industry standards. There was a subtle processing problem with this computer that I bought at the time I was upgrading my entire office network. It took more than 90 days to figure out the problem is with the processor not interacting with all the USB port effectively any longer. My IT people exhausted all resources and were not able to correct the problem. I contacted the company multiple times and they refuse to work with me and allow me to swap out part of the machine and just stand by there is past 90 days. You should not buy from this company. If you do you should buy at least a year extended warranty through Amazon. These guys are not authorized refurbisher's for anybody and I will never work with them again.
