My company had purchased quite a few of these computers and while the computers work fine all of the CD/DVD drives have now stopped working. Long story short; the tech I spoke too was very rude to me, called me a liar about what was returned and refunded. I even had Amazon call him and tell him none of the computers were returned and, despite him saying if they confirmed I can get warranty replacements for the DVD drives, he then refused to help me.They do not honor their warranty agreement. I gave them all the proof they needed and when I asked them "So before it was if Amazon confirmed you could help me, but now you can't or won't?" to which he simply replied "Nope" and hung up. Mind you, we were not asking for replacements for the computers...JUST the CD/DVD drives. I even explained these were for a radiology center and they can't work without them.
