I am comparing this to an old laptop fan I've been using, and quickly this one was beaten. The fan production was sad, even for the tiny fans that were supplied, and on the larger model. To be fair, the old fan had huge blades, but a similar price point. I was about to grab a refund, and it's still in consideration.However, the claim to fame of this device is obviously the rising mechanism. If you intend to use this fan horizontally, do not purchase, there are far better for this price point. However, the lean of this device appears sturdy, and it does add far more cooling based on that angle alone. Considering this device functions as a fan-and-riser all-in-one, and doesn't force you to buy both and attempt to connect them, this is a very functional product. I'm not yet certain this is what i was going for, but this cooling beats horizontal fans pretty much hands-down, best I'm aware.I do get the sense I hear the fans more than I should brand new, especially with the minute size of them. I fear it could develop a buzz down the road. That said, it's still quieter than my older one, for the moment, even if it appears to lack fan power to go with it.Very mixed package on this one, but still possibly a very worthwhile purchase, as long as it holds up.The fan on my laptop quit working and I could only use it for a short time before it got too hot to handle. I figured it was time for a new laptop but when I saw this I thought it was worth a try.It does a great job keeping my laptop cool. I have it on the highest setting and it's very quiet. I also like the adjustable positioning options.The only thing I don’t like is the folding piece that holds up the laptop if you have it set at an angle. It’s a little small and my laptop falls off a lot. Other than that it’s great for the priceI am pleased with my purchase of this item. My laptop runs cooler. It's quiet. I like the fact that the angle is adjustable. The stop at the bottom keeps the laptop in place. It does have 2 USB ports, but one is used to connect it to the laptop for power. Overall, I'm happy with my purchase.My daughter is using it for gaming and during school work. She loves it. Quiet and still kicking but after hours of everyday use for over a month. Great price!I'm impressed with the results and grateful.The cool-mat is extremely quiet and looks nice. I like that the connection is in the back so it is out of the way.Unfortunately it is not suitable for laps if one is wearing shorts in the summer. The bottom frame digs into the legs which is uncomfortable after a short period of time. Putting it on a board of some sort is cumbersom.Work great you will fell the coolness right away better than more expensive brandEs buena respecto a lo que cuesta, la potencia de los ventiladores es baja, esperaba que fuera mejor al ser 6 ventiladores, lo malo es que la mia se apagaba al llegar al maximo.
