I have purchased 3 dell refurbished computers.  One for my granddaughter, one for my daughter, and one for myself.  Two was sold by Skytech USA and one by Sunset Micro.  All three were excellent products.  The cases were in great shape for refurbished products and all three worked flawlessly in setup and worked as new.  I am completely satisfied.  I have had mine for close to a year now and is still working flawlessly.
