UGREEN3-Slot Vertical Laptop Stand, Adjustable & Sturdy & Space-Saving Design, Compatible with MacBook Pro, MacBook Air, and More, Fits Multiple Sizes, Space Gray

I was initially hesitant about this device due to the thumbscrew adjustments, but in use, I've grown to love it. Having three slots allows me to place my laptop, tablet, and even power supply in the stand. The size adjustment mechanisim works well, and the internal cushion supports the laptop perfectly when appropriately adjusted.

Middle slot is not adjustable and very narrow. I have many different laptops for testing purposes and I had hoped to use this product to economize desk space. While I can fit any of my laptops in the outside slots, I can only fit an older MacBook Pro in the middle slot. The new M4 MacBook will not fit in it and neither will any of the other Windows laptops I have. I bought one to try it out and had plan on buying at least 2 more, but will now have to look for other solutions. Really sucks for me. I am someone that likes to have everything matching. I may have to return this one. Pro tip: If your thumb screws keeps coming loose, you can add a drop of Loctite Blue 141 to the screw threads, and that should alleviate that issue.

It's good a little loose, but overall great
