Great for multitasking
I recently got my hands on a dual portable screen extender, and I have to say, it's pretty impressive. The size is perfectโnot too big, not too smallโmaking it an ideal companion for my laptop. One of the standout features is its lightweight design, which makes it incredibly easy to carry around. Setting it up was a breeze, and the intuitive interface ensures that even those who aren't tech-savvy can use it without any hassle. Another fantastic feature is the charging capability. You can plug your laptop charger into the screen, and it will charge your laptop. This is incredibly convenient, especially when you're on the go and need to minimize the number of chargers and cables you carry. Overall, this portable screen extender is a solid investment. It's a well-designed, versatile, and highly functional device that enhances productivity and convenience. Whether you're a professional needing extra screen real estate or a student looking for a portable second monitor, this screen extender is an excellent choice.

Do not buy!
Do not buy. Worked great for a couple days now only one screen will work at a time if they work at all. Tried with different computers so itโs the screens. Loved the concept everything easy to put away and take with you built in stands just wish it worked for more then 2days.

Magnetic interference causing onboard laptop screen video to fail
Technology great, no complaints; PnP works as advertised. Self detection worked and oriented properly (landscape) 5 star otherwise. My config: left = USBC -> USBC; right = USBA->USBC + HDMI->mini-HDMI. Problem: Magnetic strips designed to secure the metal top plate (which the laptop rests on) are strong enough to impact signaling to internal/onboard laptop screen. Makes onboard screen undetected, Windows only recognizing the F3 monitors. I'm seeing on Dell laptops - unclear if other brands are effected. Fix: Do not directly align the rear of the laptop with the top edge of the base where the monitor mounting rods are (to create that flush 3 monitor look) - instead ensure the back of the laptop sits at least an inch forward of that area. What could it be? Magnet either jamming LCD/edDP cable delivering video signal or the lid sensor being triggered.

Screen extender is time saving!
Purchased this for my husband for work. He is an offshore construction superintendent, responsible for all safety logs, personnel time, equipment trackers, emails, etc. that I knew this would make his life a bit easier. He is now able to do multiple tasks at once! Compatible with his laptop, and easy drag and drop function to move to other screens! Easy to set up, and came in an amazing package that he reuses when packing up! The screens are extremely bright and the quality has so far been great with no issues as he is probably tough on it! Shipped to us quickly! He had it all set up and functional in less than 30 mins! We are impressed!

Game-Changer for Productivity on the Go!
This triple portable monitor is exactly what I needed to boost my multitasking setup. The 14โ IPS FHD screens are bright, crisp, and easy on the eyes. I love the 360ยฐ rotation and how seamlessly it works with my laptop via USB-C. Setup was plug-and-play, and itโs surprisingly lightweight for travel. Great for working remotely or managing multiple windows. Highly recommend for anyone who wants a true portable workstation!

Great product and excellent customer service.
Purchased this product August 2025, was very pleased with it. The carrying case is extremely functional. I have had a few people coming up to me asking where they can get the setup I have. This is a great product I would recommend to everyone looking to add more viewing screens to a laptop. Most importantly, I recently damaged one of the screens accidentally. I reached out to customer service, they were amazing in replacing my cracked screen. Again, highly recommended.

I can't get the monitors to power on out of the box as other suggest
From what I read, this product is a plug and play out of the box. I have mini HDMI to HDMI on one screen to computer and USB-C to USB-C on the other screen to computer. My laptop is not detecting screens. When I add a USB-C from a screen to USB-C to my phone then that left screen is working. I think I must be missing something. Any helpful hints would be great to get both screens running. I thought all I needed to do is plug each screen to computer, and it will be powered by computer. I just unplugged the phone and connected the two screens directly with USB-C and again, the left screen is powered, but not the right. Help... I am giving a 3 as I think this will work great once I can figure it out. The right screen is perhaps faulty. I will update review is it turns to be 100% user error.
