The difference it makes!
Color: Space Gray, Size: mStand, Style: mStand, Color: Space Gray, Size: mStand, Style: mStand
With virtual lectures, I was sitting at my desk (including study time) for about 15 hours a day with excruciating back pain, so I was browsing for stands that can angle my ipad up while I was taking notes on it, so I don't have to hunch over on my desk. However, with me having to lean on the actual ipad to write, I couldn't find a stand durable enough that can support that weight without bending the stand downward. Even desk elevation platforms still required me to lean over it facing down bc of their flat designs which also caused me to have upper back/ shoulder pain.
I had the previous model of the mstand for my laptop for about 3 years now, and thought why not. The mstand I previously had was still just as sturdy as the day I first got it, so I knew I wouldn't have an issue with long-term durability. I know this company offers separate stands for ipads, but I decided to purchase another laptop mstand for my ipad because the angle of it was exactly what I wanted (plus, adjustable angles are only convenient if you're using your tablet only for viewing purposes imo). This item, being fixed at my preferred angle and being incredibly well made with sturdy metals, allows me to lean on my ipad all I want to jot down notes which saves my back like nothing else. Also, a plus is that it just looks and feels amazing. It's pretty much made out of the same metal and finish as my apple products, so it's heavy-duty and doesn't shift around at all.
I was especially impressed because this new design fixed all the problems I had with my previous design. The previous design has a slightly more elevated angle, which might not be as comfortable for some people, but this new design is lowered just a tiny bit to put less pressure on the back of your elbows while typing. Also, with the previous design I was always annoyed because the sticky rubber pieces to prevent the metal-on-metal scratching of my laptop kept falling off. However, with this new design, they increased the size of the rubber and thinned it out so that it can't fall off at all. Overall the design just feels a lot more durable and sleek.
I will definitely be recommending this to my colleagues!

Aesthetic
Color: Space Gray, Size: mStand, Style: mStand
A great stand. Does not wobble at all. I use it for work-from-home / school-from-home / create-from-home / gaming set-up. I have three different laptops I utilize on it. A 13" MacBook Pro, A 14" Razer Stealth, and a 13" HP ProBook. All fit well. I've seen this stand reviewed as "perfect for MacBooks" but I assure you all laptops would do swell.
The lack of adjustability might seem like a drawback on paper but it has sufficient height where whichever laptop placed on it is neither too high nor too low.
The space under it is great for tucking your keyboard in or your mouse. There's also a hole in the back to run your cables through. I usually run my HDMI, charger and keyboard cables through here and switching laptops while having the cables still in one place makes it a seamless experience.
The rubber nubs on the dock for your laptop add grip and even a little elevation for ventilation. Speaking of ventilation, the "raindrop" hole isn't purely for aesthetic but also adds ventilation.
Got what I expected. Quite pleased.

The perfect MacBook Pro Laptop Stand
Color: Space Gray, Size: mStand, Style: mStand
This stand is just perfect for my 16” MacBook Pro. I ordered one in Space Gray to match the MBP’s chassis. The high quality is apparent, with its sturdy build, minimalist design, and well-engineered feel — in fact, it looks like it was made by Apple itself. When I first opened the box, I thought it might be too small, but don’t let the small footprint fool you. It fits perfectly and its height is just right for comfortable work. Highly recommend!

One of the best computing accessories I've ever purchased!
Color: Space Gray, Size: mStand, Style: mStand
I know there are already thousands of 5-star reviews for this stand, but I feel compelled to post yet another one. I recently decided to simplify my life by doing away with a laptop and iMac, keeping them in sync, etc. I bought a new 15-inch MacBook Pro, configured it, and put it on this stand and I couldn't be happier!
The stand quality is such that you can't tell it from something Apple manufactured themselves. The Space Grey color matches my laptop perfectly, even down to the actual finish quality. The pass-through hole in the rear of the stand helps neatly manage any cables from the side of my laptop, adding to the overall neatness.
If you're on the fence about purchasing this product, don't hesitate any longer. It's a perfect solution to keep your MacBook Pro display exactly at eye level, and it also keeps it close to you so you can use the TouchBar. If you have a pull-out drawer for your keyboard and mouse, like I do, it's even better. I can now position the stand (and MacBook) at the exact distance I want from my eyes. Oh, it's VERY stable, and if you needed to type on it, that would not be a problem at all.

Great product!
Color: Space Gray, Size: mStand, Style: mStand
I bought this laptop stand because I am was getting tired of looking down at my laptop screen, it was hurting my neck. Now it actually has helped me create a better setup, because my laptop is elevated and when I plug in my external monitor I can use the laptop screen at the same time, increasing my desktop space and increasing productivity since the screens are much closer to the same height now. I also like the cord management, it helps keep things cleaner. The space underneath works great to hold other things like my ipad when not in use, so my deskptop is less cluttered. I bought the one that does not swivel, its pretty sturdy and solid.
