Great quality
Great quality and strong build, just big enough to store everything I usually leave on my desk like wallet, keys, glasses, pens, airpods etc. without taking up an intrusive amount of desk space.

Sturdy, Beautiful, and Functional
Color: Black
I love this MacBook stand. It sits at the perfect height (my neck doesn’t hurt anymore!), it matches the Space Black finish on the MacBook, and is very sturdy. I considered the 12 south instead of this, and returned it for this instead. Better value and better product. Overall, I highly recommend.

Fantastic Stand
Color: Gray, Color: Gray
Cooling - I purchased this stand for use in college, primarily so I could raise my laptop to the same height as my primary monitor. While my focus in purchasing this was on raising my laptop, the stand also helps cool the laptop. I have been thoroughly surprised i its effectiveness. Many times my friends and I will be working on homework together running programs such as Microsoft Teams and Mathworks Matlab simultaneously. In doing so, I will have my laptop on the stand so I can use my monitor. While my friends identical college-issued laptops are very, very hot due to the intensive tasks they are completing, mine is, at the most, warm to the touch. The only difference is that I am using the stand, and they are not. The slots in the stand, while not overly large, do aid in cooling the laptop significantly. Build Quality - Prior to purchasing this stand, I saw several reviewers mentioning the finish on the stand, claiming it had an almost gritty quality. After receiving the product, I believe those customers were hoping for a very high level of final finishing. That is not to say that it is not a high quality finish, but if you are expecting it feel like the aluminum lid of a Macbook, it will have a slightly coarser finish than that. The stand has rubber pads on all points it would contact the laptop with. These pads are mounted very securely to the frame, and I am not concerned at all about them falling off. If I would have to guess, they are made of a type of silicone and have shown no signs of wear after 2 months of daily use. They are also present on the bottom of the stand to protect the surface it is set on. The stand itself is constructed of 4mm thick aluminum all around. As such, it is very sturdy. I would be absolutely shocked if a laptop broke one of these stands. I have even used it to hold textbooks temporarily, and it has held them with supreme ease. Color - I purchased the model in the darker gray color. I did not have anything I was trying to match it with. As such, I cannot say whether it will match Apple's Space Gray products, although it looks very reminiscent of it. For reference, my laptop is an HP Elite Dragonfly with a 13.3 inch screen, and my monitor is a 21.5 inch Acer unit.

Great minimalist stand
Color: Gray, Color: Gray
Really like the minimalist design of this stand. Quality is top notch with steady material and refined edges. Had to make minor modifications to prevent laptop touching metal edges when putting on with slight angel tilt. Overall very satisfied with the product.

Simple upgrade that actually improves your setup
Color: Black
I didn’t expect much from a laptop stand, but this made a noticeable difference right away. It lifts the laptop to a much better eye level, which helps a lot with posture—especially if you’re working for a few hours at a time. The build quality is solid. It’s aluminum, has a bit of weight to it, and doesn’t feel cheap. Once it’s on the desk, it stays in place. The rubber grips hold the laptop securely, and I haven’t had any slipping issues. I’m using it with a MacBook Pro and it fits perfectly. There’s enough space underneath for airflow, and I’ve actually noticed the laptop runs a bit cooler compared to sitting flat on the desk. Overall, it’s a simple product but very effective. One of those small upgrades that you end up appreciating every day.
