After reading some negative reviews I became skeptical. Then I went to install a new program with a disc and discovered my disc drive was not functioningI emailed seller and they advised that they thought a simple phone call with a tech could resolve the issue. I scheduled call with agent Tony who was able to troubleshoot and get my tower up and running expeditiously for me.  I’m super happy they offered this service and happy to say I’m pleased with my product.  Good service is hard to find and Im pleased with the service I received on this very affordable tower.
