Grate purchase, for the price! I use this fan at minimum, 40 hours a week. It's nice and quiet, bit is very strong. It knocks down the heat on my laptop quick. It gives off enough airflow, that you can feel it while you type. The colors are awesome, and you don't lose a usb port, because it has a secondary in the back. Honestly thinking about getting a second one, for my other laptop.To be perfectly honest I have absolutely no dislikes regarding the overall experience of this purchase. Everything from the advertisement to the shipping were exceptional. But the things that stood out is the lifetime warranty and the personal contact to insure that the shipment maintained the company's criteria. I also liked the overall quietness of the fans at all of the speed modes. An exceptional purchase and look forward to do future business with Keibn.

The two USB ports means that with one being used from the laptop to power the pad, the other is available for other devices, such as my external HD. So, in essence, I'm not losing a port using this product. The height of the pad lifts the laptop in my playing environment which along with the tilt settings are a huge plus. Very light in weight, ABS plastic construction will be nice should I ever want to sit with my machine on my lap. Controls in front are easy to get to for adjustment of fan settings and lighting.To see how well it worked, I fired up one of my most graphics intensive games, set the cooling pad fans at high and called up the temperature sensing proggie on my lappie. The temperature did not get high enough to kick the internal cooling fans on my Acer Helios Predator laptop into high mode. Those guys make a lot of noise when they come on, too. So it was doing it's job. The temperatures were comparable.Now for the candy. Part of the reason I chose this particular one, aside from the price, is the lighting effects. There are 10 different settings. I thought the lighted keyboard on my gaming laptop would be nice, which it is, but it's not enough when I'm gaming late at night with no other lights on. Add the lighting from the gaming mouse to the keyboard and this cooling pad, this old man will feel like he's back in the '60s checkin' out the black light posters in friends' older brothers' rooms. During the day, I'm sure I'll use one of the settings that rotate the colors, during the evenings and nights? It'll depend on my mood.For those on a budget, like myself, I recommend this product.This was a fantastic buy; I absolutely love it. I have already noticed a significant difference in the temperature of my laptop. Prior to using the cooling pad, my laptop was very hot to the touch when I played video games. I've been playing video games for a few hours now with the cooling pad, and it's only pleasantly warm.I do wish this cooling pad was about 3 inches wider all around; the reason being that my laptop is 17.3 inches and overhangs the cooling pad. It really would be better for a 15 inch or smaller laptop. But as it stands, this worked out great for my needs!It's comfortable on my lap, it's also really easy to set up on a flat surface. Keeps my laptop super cool and doesn't sound loud even on the fastest speed (6 speeds). It has 3 settings: all fans, 2 large fans, or 4 small fans. Highly recommend! Even aesthetically pleasing, the light up around the edges and in the center makes it that much more awesome. Overall, great design!Cumple con el objetivo de mantener a raya la temperatura del computador, sin embargo el nivel de ruido es mayor al esperado, los botones para controlar su funcionamiento son bastante duros de manipular; nunca había tenido uno de estos aparatos, talvez por eso esperaba algo mas...It lights up and cold the gaming laptop does so I can play longer.Something was loose in the fans when I received it had to take it apart and fix it or I would’ve had to wait two weeks for a new one, but God knows I don’t have that kind of patience
