this keyboard be pretty nice . have illumination feature and volume control on the top . however after a couple week the spacebar start squeak when press on the right side . the volume control do not work well and I can not tell if the volume be go up or down unless I check on the desktop . overall its a nice board and it would be nice if the button on the side be programmable but it seem set for web navigation on the left side and pc feature on the right .
