Laptop tends to slip in either direction, but things are mostly okay. It has tipped over once, which was really scary because it was on a desk. Luckily nothing broke.

Holds my Dell laptop securely. Not too tight and not loose at all

It holds my macbook pro 2018. Now it is somehow flimsy sometimes I find the computer at an odd angle, It will not drop it, but once you find the right position leave it alone. I will soon replace it for the wood version Amazon sells.

You'll see this stand on plenty of youtuber Tech reviewer influencer desks understandably given it's half the cost of its round competitor from 12 South. Many of the other reviews cover most aspects pretty well, but here's one more detail. The thing about clamshell mode in MacOS, is that all the goodies that you use plugged in over thunderbolt won't be active until the computer is on an has been logged in. Bluetooth accessories by apple seemingly the exception. What this means is that you have to take the laptop out of its stand, open it up, hit the power button, and depending on whether you get keyboard activation maybe type in your password on the macbook itself. That's relevant because most stands make you pick the macbook up, hover it over with one hand and operate it with the other. Arguably as dumb as having the magic mouse 2 charge port on the bottom of the mouse, or apple pencil sticking out of ipads like a joke render for a tech reviewer's april fool's day post. I miss having a computer that has all its parts interchangeable on the inside and resent Apple promising to fix this but pricing almost everyone out of the market and leaving us in a perpetual dongle hell of daisy chained points of potential failure. But this stand makes this one part of dongle hell 2% less annoying, which is more than most of the competitor stands. Would like to see a next version include rubber flex in the middle that's thinner and wider base on axis of flex.

Pros: Less expensive than direct competitors with similar fit and finish, rubber flex accommodates many different models and also allows opening for power button use, anodized finish a good match (to macbook space grey)

Cons: not a wide enough desk footprint on axis of rubber flex to feel as sturdy as possible, rubber flex portion a little wide for newer macbokks (some wobble)

When I received the product, I thought I bought the other HumanCentric vertical stand (model 401-1024-S) but realized I got the model that doesn't have the extra silicone pads to add to fit your laptop. Instead, when you put the laptop into the groove, the holder bends inwards to clasp your laptop. It works okay, but I can easily move the laptop back and forth. I decided to keep it because the other model apparently doesn't work that well with the 2023 Macbook Pro 15".
