Bests & Worsts Reviews from Amazon

I am so disappointed. I have tried several of these thin/portable monitors... I can say this one lasted the longest (purchased almost 4 months ago). Unfortunately that also makes it the worst because I was able to replace and return the other one(s). It worked so beautifully until about a month ago. I started to see it glitch a bit. It only got worse from there. Everyday trying a different location for the cord to rest for it to work. Now it only stays on for a minute or two. I assume its the ports inside the monitor(s) that is the source of the issue. They must not be secured well enough so the constant plugging/ unplugging wears out the port...?? If this is correct it defeats the purpose of a portable monitor. *Looking for a reliable portable monitor. *
