I bought it a few days ago. I have a laptop with a 15'' screen, which means there is little space around it. From the space left over, air passes towards my hands. I don't know yet if this is annoying. Its noise is less than the noise of the laptop. Its plastics seem sensitive. I have the impression that with one wrong move they will break. It is taller than I expected. The positions it has for inclination are many, but the smallest angle available, apart from the parallel one, is high. I give it five stars because as a product it is exactly what it says and also it is my first contact with this kind of product. Unfortunately for me, it does not meet my expectations since the temperature, according to a third-party app, dropped from 89° to about 75°. I had the impression it would drop more. I recommend it for someone with a low budget. I will keep it as long as it works, but next time I will spend more money.
