Very decent cooler and stand for laptops up to 15.6 inches. Almost silent, barely noticeable, don't be fooled by the cheap construction, it is durable and cools effectively, for a regular user it is ideal. I've had it since 15/11/2020 and it still holds up. The only thing to be careful about is the fan underneath which is completely exposed, so make sure it doesn't come into contact with objects or any obstacle, so you can't hug it and play, it needs to be on a stable and smooth surface like a desk for example. The feet are sturdy, even the cable, although when I first saw it I thought "okay, it's flimsy, I'll give it a week before it breaks" still works just fine and it doesn't consume much energy for its use (the laptop battery lasts almost the same whether I have it plugged in or not). I have a low end laptop with an AMD Athlon Gold and it keeps it at good temperatures, even when I don't have the USB plugged in just from the good airflow created by the stand due to its design. The best 5€ I've spent. (and I would pay even more now that I know how long it's lasted me)

For its price, you can't expect something better but...

a. The stand, although it claims to be suitable for 15.6'' laptops, sticks out and the cable doesn't reach the USB ports. If you place the laptop on top so that the cable reaches, then the fan doesn't "catch" where it should to keep the temperature low.
b. The cable is quite short and only passes through the back side of the stand, which makes the cable look small (and it actually is since there is no alternative). Any other solution results in the cable obstructing the fan.
c. The cable is integrated, so if it breaks or gets cut, the whole stand becomes useless.

We bought 2 and had to return one because the 15-inch laptop didn't fit on it. Everything was fine with the 14-inch.

For a 15-inch+ laptop, I believe spending a little more for something bigger/better is the better choice
