Underwhelming
Color: silver
Too much hype. It just holds the laptop. Buy something cheaper. The slide adjuster isn’t useful to me at all.

Useful but not perfect
Color: silver
Useful, but typing with laptop perched on it is unsteady. I use a separate keyboard.

Why are people trying to type on a laptop stand?
Color: silver
So the overwhelmingly negative reviews you'll notice for this product specifically surround the "bounciness" of this stand when someone is typing on it—however what is confusing to me is how people are purchasing a laptop stand in theory to optimize their ergonomics, yet also stretching their arms out and elevating them to type on said laptop once it's raised. the point of a laptop riser/stand is to elevate the screen so that you can maintain a more natural posture. One would assume you have an external keyboard to use in conjunction with your laptop once you place it on a RISER, because the idea is to elevate your laptop as a SCREEN and then have a level/flat surface to type on, thereby alleviating any awkward hunching or neck strain looking down or anywhere not naturally eye-level.
as it is, it's a perfectly functional and elegant laptop riser. I don't find myself wanting to adjust the height often if ever, but in the one or two instances I experimented with it, found no mechanical issues. It looks nice with Apple hardware and allows me to have my laptop's screen flush with the bottom edge of my additional external monitor, so it serves my purposes well.
for people complaining about how it bounces when they type on it ... STOP typing on your laptop's keyboard when you have it elevated on a riser! this defeats the purpose and probably also makes your arms tired—buy an external keyboard!

Perfect Nightstand Organizer and Looks Amazing
Color: Dark Brown
This valet tray is exactly what I was looking for. The wood looks great and feels sturdy, and it keeps all my everyday items in one place. I use it for my keys, wallet, watch, and phone, and my nightstand looks much neater now. Its great to keep all the thing you need when leaving the house in one place.
It’s the perfect size, well made, and looks nice enough to leave out on display. Would definitely recommend this if you want an easy way to keep your essential items organized or need a solid gift idea.
