Don't buy HP. I bought their DVD writer last year. It worked for about a month (only on HP media) before conking out. After about 20 maddening hours on the phone with tech support, where they refused to reimburse me and insisted that I buy HP media before they would accept that it didn't work, I was able to prove to them that it was faulty. My only option: ship it back and get a replacement. No refund. So I did that. And the second one didn't work at all. After another dozen hours wrangling with customer service, now outsourced to India, they outright refused to reimburse me. I threatened to sue, and got a fax number where I could send my receipt for a refund. It was a nonexistent fax number. I called again and got a different number. I never got a reply. I sent emails and faxes for a month before finally giving up. I am taking HP to small claims. Never buy HP. Take it from an insider.
