Sincerely for its price, it perfectly fulfills its mission, yes the blue light may be painful, but if you do not specifically need the USB is not put food and it still serves to hold the mouse cable .. .
In short very good product, no need to paste it on the ground like good and mouse cable is easy to remove and hand ...
Anyway I'm pretty RAZER regarding mice and keyboard but there razer of the cable holder meant nothing to me, it is really good!
