I got this for my spouse’s HP 17 in. laptop. His laptop is always overheating and turning off, which is very inconvenient if you are in the middle of a game or surfing the web. I had bought him one for home and instead of carrying it back and forth , I thought this one would be great for camp. The fans have helped keep his laptop cool and it has cut down on his fan constantly running like it is going to take off. It has not overheated at all and turned off. The fans are really quite and they are not super strong but they get the job done. The LED lights look really cool but if you have a 17 in laptop you can not really see them. Has two “feet ” in the back that open if you want to tilt the back of your laptop up. Has an on and off button in the back and 2 USB ports ( one to plug the fan into your laptop and an extra to replace the one you are using if needed ) . Comes with the cord needed to plug in from laptop to fan. Comes on as soon as you turn on your computer and shuts down when you turn the computer off. The only con is you can not turn off the LED lights when the fans are on…which can be a downside if you are trying to sleep. I received this product at a discount. All my reviews are based on my experience and evaluation of the product.so others can benefit in finding quality products that meet their needs and expectations.
