Mobile Pixels 12.5" Duex Pro Portable Monitor (Open Box)

My monitor crapped out after two days of use. I spoke with an Amazon tech consultant who said it sounded like there was a problem with the device and suggested I exchange or return it. I asked for a refund. Here's what I thought before it died: (I have a 2017 13" MacBook Air.) PROS: *Wasn't hard to set up. *It's portable. *I didn't want a monitor to take up much space, and this can even hang over the edge of a small table. Cons: *It costs a lot more than an economical larger monitor. *The screen quality is good enough but could be much brighter. *When it's attached to the back of the laptop, it can't sit flush. It has to hang over one side a bit to allow the screen to swivel. No big deal, but it looks clunky. *It is easy to remove the monitor from the laptop when it's not being used. It attaches with magnets. The metal discs that adhere to the laptop cover, however, are meant to stay on the laptop, and they add considerable weight. This compromised the lightness of my MacBook Air. They are also unattractive. *You have to use a blow dryer to heat the glue to remove the metal discs. I didn't feel comfortable attaching them to my laptop directly and bought a cover, which also added weight. (The blow dryer worked, and there were no marks left on the cover when I removed the discs.) If the monitor worked I would have kept it and hoped that someday there would be a more elegant model.
