Summary: We have about 200 of these monitors and the failure rate is about 50-60%. It's often difficult to gauge the reliability if you order only one or two because bad monitors are probably chalked up as a fluke and quickly replaced by the company. I can definitely attest that these monitors are ticking time bombs just waiting to fail (probably right after the warranty expires!
Summary: Do not buy this monitor. I bought about 12 for our company and the failure rate is about 60% now. Of course just after the 3 year warranty, they started failing. They are in a contolled environment were other monitors also exist with no trouble.
