Awesome product only thing that worked
I originally thought the Screen Buddy was overpriced, but after spending hundreds of dollars trying to perfectly align my monitors for sim racing, this is genuinely the only thing that has actually worked properly.
Triple monitor alignment is one of the most frustrating parts of building a sim rig, especially with monitor arms constantly moving or sagging. This finally made everything line up the way I wanted.
Expensive? Maybe. Worth it after all the headaches? Absolutely. Great job.

Doesn't stick
The adhesive tape kept coming off. I cleaned and followed the installation instructions, but it still kept coming off. Wouldn't recommend.

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.
