This item is very cool, I'm very impressed!!
It's a 14'' portable device for a laptop, and I was very impressed with its performance and ease of use. This screen extension tool is a game changer in improving productivity and multitasking capabilities, especially for someone like me who constantly switches between apps and windows. The first thing that caught my eye was the seamless plug-and-play setup. It was easy to connect to my laptop, which ranges between 13'' and 17''. Compatibility with Windows and Mac systems, as well as PS5, shows the versatility of this device, making it a perfect choice for a wide range of users. FHD 1080P resolution delivers sharp, clear visuals, making every detail stand out, whether I'm working on spreadsheets, watching videos, or playing games. The addition of internal speakers was a pleasant surprise, offering decent sound quality that enhances the overall experience without the need for external speakers, I really like this product, very cool and easy to use!!!!

Perfect for the Workaholic
A year ago, a friend told me how they loved their brother's multi-monitor setup after using it and wished they could have it. This friend had always helped me out in a pinch, so I wanted to get an extended monitor for them. But I wanted to surprise them - all I knew was that they owned a Macbook but I didn't know the size. When I saw that it could stretch to a variety of laptop size supports, had a stand in the back to support the weight of the monitors, and a carrying case, I knew it would be a quality product and a viable gift for people on the go. My friend loves it - it's a functional, practical gift. The monitor display quality - vibrancy, colors, brightness - were all good. Because there's a carrying case, they could bring it in case they want to station at a cafe. The only caveat is that the laptop needs to be plugged in the entire time as the monitors do drain the laptop much faster.

Only One Side Works
I bought those to help with schoolwork and work. But it doesn't matter how I connect it, the second monitor will not turn on. I connected it every way the instructions said to, but it didn't matter. Then of course, by that time the deadline to return it had already passed, which is really disappointing as the amount of money spent was rather large amount for only half of it to work.

Great product! Instructions? Not so much
Product is great however instructions to assemble it were horrid. Need clearer more detailed instructions.

Great Laptop Extender!
I needed some extra real estate for my laptop since it’s only a 14” screen and decided to try this extender out and it is just great. The quality of the product far exceeded my expectations, has a good weigh to it without hindering the ability to just rest it on the laptop screen. It comes with a ton of cables that allow you to set it up to almost any device (PC, phone, Nintendo Switch, etc.). There is a travel case that it folds down into for when you’re not using it and works great for keeping it safe. The picture quality is excellent. Yes, it’s only 1080p but at this screen size the pixel density is far beyond what the average person needs. Also, with it being only 1080p my laptop isn’t super hot trying to keep up with the resolution. Overall, this is a great extender and highly recommend it!

Great idea, but not as easy to connect as shown
I really like the idea. The product seems solid, but the instructions were lacking a little more detail. The C to USB option did not work at all. I would have to go and buy more chords and/or some sort of docking station to make both screens work, which now makes me have to carry even more things. (reducing the idea of portability). Overall, I really like it, but a little more difficult and requires more items to purchase to make it work than advertised on my system.

more screens means more productivity
I use 2 external monitors connected to a laptop when working from home, giving me total of 3 screens. I've been using multiple screens for years and I just can't use the single screen on the laptop anymore as I need more real estate screens to be able to open and view more apps at the same time without having to minimize or search for them. I started to commute and travel for work at least once a week so I have to bring my work MacBook Pro with me and I usually get stationed at an empty cubicle or a table inside a conference room without any monitor. So this 14" triple monitor for my MacBook Pro was perfect for my need whenever I needed to go into office so I can still have 3 screens in total. It was well packaged with the retail packaging box that was double boxed for extra protection. It comes with all cables needed to connect to different ports and types of laptops but for my MacBook Pro, I just needed to use the USB-C cable for each screen. The spring loaded middle body frame easily sits around my MacBook Pro screen and the adjustable kick-stand on the back allows it to stay in the desired angle without the screen falling back due to the weight of the 2 side screens. I really appreciate the dial button on top of each screen to access the on-screen menu for adjusting settings, and the travel bag that it comes with is perfect for my need whenever I need to take this dual screen extenders to work. Love these screens and highly recommend it to those who are frustrated having to minimize applications to switch to different app. I can now have many different apps opened on different screens and can easily find and see at a glance. Highly recommend it.
