Great for on the go
This has been a great for travel. The instructions were not the best but once you realize where the wires go its easy.

my on-the-go work setup.
The setup was a breezeโclear instructions guided me through the process, and it was up and running in no time. What impressed me most is the plug-and-play feature. No fiddling with settings or hunting for drivers; just plug it in, and you're good to go! Itโs compatible with all my devicesโfrom my MacBook to my Windows laptop, it handled them all like a champ. The slim design means it fits perfectly in my bag, making it an ideal travel companion. The picture quality is sharp, and the colors are vibrant, which makes working on it a delight. The resolution is goodโthough one of the screens has a slightly lower resolution, it still delivers a pretty solid display. Price is fair so far

Beautiful screens and a big boost to productivity on a laptop, but heavy and bulky
My work is computer programming and a big screen or multiple screens is huge productivity boost for me. I've always considered getting one of these for the rare situations where I'm traveling and still need to do a significant amount of work. While this is cumbersome in that it's essentially a second laptop bag and pretty heavy, it's usefulness is undeniable. The screens are sharp and clear. If you're planning to do any kind of graphical work on this setup, you'll need a color calibrator. The color in the background image was visibly different between my laptop and these screens. The monitors have a kind of both sturdy and fragile feeling. They're heavy but delicate so I am a bit worried about breaking something when I move them around. Setup was easy, but the directions were somewhat lacking. It wasn't clear whether the USB power should be plugged into USB1 or USB2. Maybe it's either? At least the HDMI (which was also USB) was labelled. The power requirements weren't fully spelled out in the back as normal, but it's mentioned in the text that it requires 2A. My laptop is pretty old because I don't use it often, so I didn't have the connections necessary to run both screens at the same time, but the laptop could power one screen without needing an external supply. I'm planning to replace that laptop soon and I'll make sure that it can run both screens because after trying it, the extra real estate really makes a big difference. The packaging was excellent, lots of sturdy foam to protect the monitors and organize all the cables. It doesn't appear that the two screens are connected electrically in any way, it would be nice if you could detach one and leave it at home if you only want one extra screen.

Works for me
I bought this for my office as using multiple apps on my laptop can be pretty tiring on the eyes. I have a Dell and it works fine for me. I read that people have issues with their apple device but for my Dell, works fine. Perfect size for me and pretty standard hi def pictures. Easy to setup and I have the overall quality for the price. I use an external speakers with my laptop so it all works well for me. No issues so far

Greatest investment ever.
I work from home and I have been working with external monitors for so long that I canโt work without monitor. This extended display is a blessing. It has an excellent display. Itโs easy to assemble. Size wise it weighs and its size is same as a regular laptop. Hence itโs like carrying two laptops in a bag . But it offers great convenience.

Very useful for multitasking
Pretty easy to setup. Clear instructions given. Been using it for two days, quality is pretty good. Speaker quality is great. Screen resolution is good too (though only one, other screen lower resolution but still pretty good). Very portable as well. Overall very happy with the product

1st 2hrs screen stopped working, and seller did not contact me back!
1st 2hrs screens stopped working, and seller did not contact me back! I paid 200+ dollars and can't even get a reply. The only thing I was told was amazon can't contact them and I can't receive credit I can only return and wait 30 days to get my money back! I need the screen now for my work and I feel like they got me for my money.. came looking for a great product and left getting robbed!! never shopping here again and wouldn't suggest it to anyone else!
