I was very happy with this cooler at first. It kept my laptop runner cool as a cucumber. Some people have noted problems with the feet that elevate the notebook, but I've had no such issues there. I am though not happy with the very bright blue light that stays on when its in use. It's very noticeable and annoying to me. I ended up using a small piece of black duck tape to cover the light which has worked well, except that now theres a piece of duck tape on an otherwise aesthetically pleasing device.Now the big problem. After only having it for less than 2 months it has started making this horrible vibrating noise. It's as if the fans are not balanced or something. But whatever the case, it's a major killing point to what was a great item. I'll be returning to it amazon.
