Works Great, Very happy customer
I’ve tried a few different ways to connect and manage dual monitors, and the Screen Buddy Dual Monitor Connector is easily one of the most straightforward and reliable solutions I’ve used. Setup was quick—no confusing instructions or extra headaches
Performance-wise, it’s been rock solid. The connection stays stable and even when I bumped the monitors once, and they disconnected, it was a quick push and they clicked right back together.
Build quality feels solid and durable, not flimsy like some cheaper connectors. It’s clearly designed with everyday users in mind, whether you’re working, gaming, or multitasking across multiple apps.
Overall, it delivers exactly what it promises: a simple, dependable way to keep your screens connected with no gaps or one being too high or too low. Definitely worth it if you want a clean, hassle-free dual monitor setup.

Warning, if you have two different thickness of monitors these may not work as intended.
The product seems very well made and the adhesive is very strong. These seem like they would work really well if you have two monitors of the same thickness, in my case I did not and they actually created more of a gap then without.

Surprisingly Amazing!
Color: Walnut, Color: Walnut
I bought this expecting it to be a cheaper product I would use until I bought something better. I was very surprised to see how nice it was! Very solid and non slip surface on the bottom. The wood on it looks great and one of the most awesome things about it is you can manually adjust it to fit your laptop. I have a heavy16 inch MacBook Pro with a case on it and it fits perfectly in this stand, after adjusting it, of course. I ended up buying another one for my work office too. I can’t wait to try other products from this company.

INCREASED DESK SPACE - ORGANIZED
Color: Walnut, Color: Walnut
I just received my new Vertical Laptop Stand by UPERGO! I had no idea that this device could free up so much space on my desk! AND, it looks great, very rich & professional with the solid wood, Walnut dividers. It has solid weight so your laptops won't just tumble or slide away either. The dividers that hold up to 2 laptops will also hold your cell phone. What an clever invention by UPERGO!
I am now able to keep both of my laptops in the same space which frees up substantial workspace for me. The feature that allows me to adjust the width for different sized laptops is GREAT.
I was at wits end how to add ventilation to my laptop as it became so hot. It now runs much, much cooler because the fan/air flow is vertical as opposed to flat on my desk. So many improvements in just one device. Thanks to UPERGO for this fine device which makes my desk look better & so much more functional!
I highly recommend to anyone that spends time with laptops at their desk!
