Pretty cheap but surprisingly solid
Color: Black
This thing comfortably fits my 16” MacBook Pro. It does tilt a bit probably due to me screwing it to the underside of my wooden desk which probably isn’t the exact use for it, but it holds really strong and isn’t going anywhere. Combining this with a small USB-C hub for some USB As and and extra HDMI and a little bit of Velcro, this holder makes for a pretty solid option to hide you laptop away if you a surprisingly clean desktop-like experience, even if you’re on a budget and can’t afford a desktop. A proper thunderbolt docking station would go a long way with this as well.

Works as advertised
Color: Black
Functions as described. Looks good. Laptop fits in loosely. I’d prefer a more snug fit. Other than that, works as advertised.
