Review on Trio 14.1-inch Portable Monitor, 1920x1080P, 60Hz - Maximize Your Display Experience! by Jeremy Dobson

I wore it for about an hour and it hasn't fallen off. It doesn't seem very secure for a laptop but it's ok, I plan on getting extra magnets for it. I bought it new used for $190 and I don't think I would have paid the full $300 for it. Just because the screen is small and sways slightly. I would say it's 80% safe on a laptop. But I think that additional magnets will solve this problem. Although the screen quality is excellent. Would recommend but not at full price. Get a new used one and I think you'll be happy.
