Works as advertised, but included USB-C cable was defective.
Size: 15.6" 1080P
This monitor performs great! Picture quality, brightness, all work as expected. When powered by a phone, you may have to limit the brightness below 80% if you don't attach extra power. The good news is, I can attach a power bank for the extra power, and any extra power not needed by the monitor will pass through and charge my phone.
I've tested this with my laptop, phone, and tablet, and it works great in all cases. One extra plus that I didn't expect, because it was not listed in the product description and also not mentioned in any reviews that I saw, is that this monitor has VESA compatible holes for a VESA mount hidden behind the magnetic cover on the back. Beautiful. If I ever decide to mount it to an arm I can do it.
All the advertised functionality works as expected with ONE exception. The USB-C cable that came with this monitor was faulty. It had a short across a couple of wires which could have caused damage to my phone had my phone not recognized it and alerted me of foreign object or water in the port. That water and foreign object warning basically means something is causing wires to be connected that shouldn't be and assumes you have a good cable. In my case, it was the cable itself that was faulty, and I used a tester to make sure.
While the description says "do not use other USB-C to USB-C cables", that is just to cover themselves, because many people will use a USB-C cable meant only for charging, or one that is not display compatible. I have cables of varying lengths that are Thunderbolt USB-C which all handle between 100-240W power, data up to 100Gbps, and displays up to 8K. I just used one of my cables and everything works just fine. If you're having trouble with your monitor, or intermittent connections with the monitor (I did before I got the warning) then you may have a bad cable. Get a quality cable and make sure it's rated for display port, high data throughput (ideally minimum 40Gbps), and decent power capacity. Some will work for data but not power. Some work with power but not data. Some work with power and data, but only one at a time. You have to flip the connector to go between modes. I don't know why they make those, and those that manufacture such garbage should be locked up, but that's another story for another day.
Bottom line is this. It's a quality monitor. If it ever starts having issues, I'll update the review. The cables I'm not so sure of. The HDMI cable is sufficient enough for FHD display, but I wouldn't recommend swapping it over to a higher res monitor, as it probably can't handle it. The USB-C cable has quality control issues, as they sourced out inexpensive cables for this monitor to keep the costs down. No big deal for me, as I have an abundance of good cables, but keep that in mind that you may need to consider the cost of quality cables for this monitor.
I'm glad I bought it. It's going to make me much more productive. While I was disappointed in the USB-C cable, it's not a deal breaker as I already had plenty. Minus one star for the bad cable.

Versatile, Great size, great value and bright. A little heavy, but well worth the cost.
Size: 15.6" 1080P
I own two of these monitors, I have been very happy with them. I carry them in my backpack/laptop case with all of my needed accessories, and it just simply works.
I work from home and I was looking for something that I could take with me when I travel. My typical home setup involves a 43" LG monitor in the center, and then four additional 1080P monitors. When I am on the road, I need something smaller to have more "real estate" to work with. I usually use a hotel 4k TV or 4k tv at the air BNB we stay at so that I don't have to the 43" LG, but sometimes I just use these two portable screens. I have held meetings from a roadside park from the back of my Suburban with these while we were camping, from Panera while mixing audio, from a waiting room at an office while waiting on someone to complete their day, etc. All in all, the two that I have allow me to streamline my workflow when travelling. I have multiple windows up during the workday; I gather information from those screens and consolidate/copy/paste/ reference the data on my main laptop screen in the front and center. These monitors simply allow me to replicate what I have at home, but on a smaller and (somewhat) lighter scale.
The good: I am not a gamer, so I cannot comment on how these would work in a gaming setup, I work on documents and reporting. With that said, these have great color at a great size. I can fit my Macbook Pro, and up to four of these screens in my bag, plus all my accessories, including Jabra Engage 75 headset, Plantronics headset (backup) , Apple keyboard and mouse, StreamDeck, USB-C Hub, and when needed, a universal Docking station that uses DisplayLink technology (Dell UD22) to get the extra screens. Without that, the Mac won't support more than 3 or 4 displays (Check specs for your PC/Mac). I like that these are USB-C *AND* HDMI. I can use them on pretty much any modern PC. To use the HDMI, however, You do need to power the monitor over USB-C with the provided cable. That's not a product issue, it's simply because that's the way HDMI works, there is no power over the cable. VESA capable, which is a big plus, I have magnetic VESA arms and I leave the plates on these monitors so I can use them anywhere.
The bad: The rotator dial on the side has a tendency to get smashed in, but I don't use audio on either of the screens. I have a Bluetooth noise cancelling over the hear headphone set for that. A more solid design would have been with tactile push buttons instead of the rotator dial. I only have this problem with one of the screens. When I put them the backpack, I now put them in with the rotator dial pointed up to ensure a drop of the bag doesn't chance damaging the equipment.
The ugly: The weight of the screens and associated covers adds about 2.5 lbs each, which is a lot. I have ordered two more, so that will be 10 lbs in the laptop backpack. May need to switch to a roller bag to cart this entourage around.
Once I get the other two, I will revise this review. Right now I don't know if I will have to use the UD22 to utilize all of these screens simultaneously.

Great product for a great price
Size: 15.6" 1080P
I REALLY like this. I need 2 screens to do my job efficiently and have struggled lately when traveling. Splurged on this for myself and was really impressed. It’s nice and lightweight but feels sturdy. The image quality is good. The set up could not be easier. This is a game changer for me.

Works pretty well for a cheap monitor
Size: 15.6" 1080P
I work remote and travel, so I miss my multi monitor setup. Not anymore.
I took this on a trip with me and it was great. The stand folded over to not take up too much desk space, the cables wear just long enough, another 6” would have been great but they worked.
Quality of the screen is plenty good enough for office work, I have no gaming or artwork experience with it though.
If you need an inexpensive 2nd monitor , this works great for on the go or even for a regular desk.

Great portable second screen
Size: 15.6" 1080P
Really convenient for a second screen on the go. The display looks sharp and it’s lightweight enough to carry around easily.
Setup is simple, just plug and play. Not super bright, but works well for most uses.
