Just received it.
I need it for when I take out the Thinkbook 14" on the balcony table, which has a glass surface.
I also have a Deepcool U-Pal, which is not convenient inside out.
Construction as expected.
What I didn't expect is that when I have it completely flat, it is convenient for me on the desk as well, as it slightly raises the laptop, allowing the fan to get air and has a small angle that facilitates typing. This was a disadvantage that another stand had.
Second positive, it fits in the backpack without any problem.
Third, it doesn't require a USB port.

If any negatives arise along the way, I will write them.

5 stars and I highly recommend it.

Nice gadget, I bought it for work. It can't hold more than x weight, so the more weight we place on it, the harder it is for it to stand on a high level. Overall, it's very good and I am satisfied.
