Query: Beware

I ordered this monitor because the other reviews said it was a good deal. Big mistake. The first monitor they sent me didn't work, so i had to send it back. Then then sent me another monitor, and this second one is barely usable, as the screen flickers almost all the time. Because I didn't want to go through the bother of sending this one back again and possibly getting an even worse monitor, I am learning to live with it.I wonder if all these other reviewers are actually real people who bought the monitor or whether they work for the company that sells it. Do not trust them. This product is terrible. Spend an extra 150 bucks and buy a real monitor from dell or another reputable company.
