The first monitor lasted six hours before it broke. However, PBTech replaced it quickly and the second one is working well. More annoyingly, the monitor only came with an S cord - it did not have an HDMI cord. This meant that to get it working correctly I had to go to the store once to pick up a cord, and again to replace the monitor. However, now I have a cord and a monitor that is not defective it is working well for my purpose.
