Excellent Product - USB C - power and data transfer!
Color: Black
It works great. I used this to connect two USB-C devices: one from the POS printer and another for charging, both connected to my tablet into one USB-C. It solved the biggest issue that I was facing.

Great replacement screen for an old Chromebook
Size: 15.6" 1080P
Needed a new Screen for an older touch-screen Samsung Chromebook that bit the dust. Repairing it wasn't an option since it's no longer available. Enter this gem of a portable monitor. It works great. Not a replacement touch screen, but works fine with the chromebook touch pad or mouse and dongle. Easy to hook up, a bit testy on first several attempted to bluetooth connect, but works fine now. The speakers leave a bit to be desired, but I just use Bluetooth speakers anyway. Overall, very pleased with the screen clarity and responsiveness of this portable monitor. 15" screen. Great value! I'd buy it again.

Exceptional - Better than one twice the price
Size: 15.6" 1080P
I bought a different external monitor a few years ago for twice the price and it was abominable compared to this monitor. This monitor is absolutely perfect. The speakers are definitely tinny like others mentioned, so don't expect to DJ a party with this thing, but for work it's perfect since that means voices are clearer anyways. The sound just isn't as full/rounded with proper bass, but it doesn't even matter because there's also a headphone jack on the monitor, too. USB-C is a total game changer for powering and passing full audio-visual in a single port. The included cables are also a big win since getting a spare data USB-C cable can get pricey and I know the one included is guaranteed to work with this monitor. It was literally plug-and-play with my 2023 16" Macbook Pro. I could go on and on about how every detail of this monitor is perfect, like how the stand is also a screen protector cover and how light and easy it is to carry and how the little grippy feet hold it in place confidently, but my point is THIS is FINALLY the external monitor I've been looking for!!!

Great purchase and recommend!
Size: 15.6" 1080P, Size: 15.6" 1080P
What a great product! First I’ll start by saying it’s very lightweight which is what I needed to fit in my bag. I bought two of them because I need three screens and I couldn’t be happier. Set up, one cord!!! No power cord needed pulls power from the laptop so that’s a huge win in my book! I love the size I love the case is attached. Definitely recommend
