Definitely pick one up!
Color: Black Walnut, Color: Black Walnut
This stand looks great, the material has a nice finish, and the quality is really good. It holds two MacBooks very comfortably. It doesn’t take up much space and has a good weight to it so it will not move easily. Great buy!

Finally a dual vertical stand with a stable build, quality materials, and snug fit for MacBook Pro
Color: Black Walnut, Color: Black Walnut
I don’t normally write reviews but I’ve had so much trouble finding an adequate vertical stand for two MacBook Pros that doesn’t worry me every time I look at it. I can finally say with confidence that I won’t need to replace this one. Not only is this stand attractive, it is simply a lot more sturdy than the all-metal “industrial” stand that it will replace because my MacBooks fit into it without wobbling, it has a wide surface area base, and its overall fairly heavy due to a solid wood + solid metal build.
This vertical stand stands apart in the two areas that my previous two stands have failed at:
1. A snug fit with a protective lining so that the laptops don’t wobble and bump into each other (the dual Omoton I have suffers from this terribly where the laptops bump and lean against one another)
2. A solid base with enough weight to prevent the stand from tipping over from an accidental bump (my single-laptop human centric mount is beautiful, but the base is too light and narrow so that any decent contact feels that it might tip over)
This stand has a very solid build quality with a nice weight to it which is comforting when potentially storing two expensive pieces of hardware in a vertical orientation that lends to tipping over (MacBook Pros are absurdly well over $2k a piece now on average). This is now the third vertical stand I’ve purchased for my two MacBook pros (work & personal). It’s not my third because I compulsively purchase things I don’t need (though I do do that), but rather because the previous two models felt unstable and carried a greater risk of damaging a few thousand dollars in equipment.
Anyway, this is my first purchase from this brand but I highly recommend!

Perfect for laptops, tablets, Remarkables, Kindles - you name it! This dock is perfect!
Color: Black Walnut, Color: Black Walnut
Coming across UPERGO has been a blessing. To find items of this caliber without having to pay a mortgage payment on it is a lifesaver. It truly is, and I have found that based on my desk setups in my office, UPERGO has not let me down with any of their products. I had already previously owned a UPERGO Vertical Laptop stand. I use that one for my productivity desk for my work laptop and my personal gaming laptop. So, I knew its quality was legitimately top notch already.
The problem I ran into was a workflow issue. I have four portable devices that I carry every day at some point: Microsoft Surface Pro 13", Remarkable Paper Pro, Remarkable Paper Pro Move, and a Kindle Colorsoft. The problem is that I did not want to keep them inside the desk drawer that I use. So, I need something to help save some space on my desk and sort of dock these items when there were not in use. I set one on each opposite side of my desk and that worked out perfectly. I was able to save desk space but also add a bit of protection for these devices. I could adjust the slots, if needed, but it worked out just fine. And the material inside gripped these devices perfectly.
Once again, UPERGO has been able to build a product that fit ideally into my use-case. This time, albeit in a slightly different manner, but it was exactly what I was looking for.
