Portable retail Monitor

Product Name: Portable retail Monitor
What a waste of money on this monitor. Supposed to be a simple plug and go type deal but that's hardly the case. I tried out my phone and sometimes it works and sometimes it doesn't work and i have the Samsung Galaxy S10. I got my Nintendo Switch to work one time and after that it just flat out would never work on the monitor again. Don't get me started on the volume because a pin drop is way louder than the crappy speakers that this monitor has to offer, absolutely horrible sound and you can barely hear it even in an all quiet room. I have to say I was extremely dissatisfied with this monitor and retail had to return it.
