For the price, you just cannot beat it. However, the LED barely lights about half of the keyboard, and the flexible neck is too loose and thus you need to be careful not to bump it when in use to avoid the light from tipping back onto the screen or forward onto you hands while typing. It definitely helps to shed some light on your keyboard in dim light conditions, and does stay cool to the touch.-- In the end I need to mention that although this is a low cost item, in turn it is still not worth the consideration. After all was said and done, the flex neck on this unit is way too flimsy, and I found the base where the USB attaches to the flex neck was not able to support the weight of the product. The unit did indeed fail at that weak point, exposing the wires, and then snapping them. I am currently in the process of replacing this unit - DON'T WASTE YOUR TIME!
