As others have written, it is not for a 17-inch laptop, barely fitting a 15.6-inch one. The plastics are of very poor quality and when you make a movement, you have some fear. As a construction idea, it is very good but not of good quality. Well, what do you expect with 15? I have an Esperanza which is better and of higher quality for half the price of this. Also, it is quieter than this one. Because this one makes noise. A positive aspect is that it has a power outlet for the fans

The size it claims has nothing to do with reality. It mentions it's for a laptop, but it's suitable for a notebook. And the box says notebook cooler. It is very small. Do not buy it thinking it's suitable for a 17-inch laptop.

WARNING.

The product has misleading inches that do not correspond to reality in any way. The base is definitely not suitable for 17 inches, let alone for 17.3 as stated on the box. It is excessively small in both length and height. The laptop does not sit on the base at all. Do not make the mistake of buying it because you may not be as lucky as me, who got a refund. In any case, if you absolutely want to buy it, ask the store if you can try it out. The length I measured before returning it was 37 centimeters, I did not measure the height but compared to the base I currently have, it must have been around 24 centimeters. Be very careful.

Other than that, it has 6 adjustable fans in terms of their speed, and at the same time, the brightness is also adjustable. The less they spin, the less light they emit and vice versa. This is achieved with a wheel next to the 2 USB ports. If I had a 15-inch laptop, I would definitely buy it, even though the fan speed was not satisfactory.

Quite good for its price, I have had it for 2 months now and it works perfectly fine. The only thing I would like is for the fans to work faster. They can be adjusted, of course, but even at maximum, I don't think they are sufficient, especially for the summer.
