Not worth your money. Switched to wireless low-profile mechanics costing 30% less than the subject. Yes, it is noisier and discharges faster, but it works without jambs, it has an all-aluminum frame and a normal ANSI layout. Different pros: Key mechanism, noiselessness, battery life (I used the backlight infrequently). Cons: Layout, price, plastic frame, location of function keys (glued together and shifted due to long Esc), sometimes the volume up button stuck until you turn off the keyboard (which is critical, because I use a DAC with a large margin of power, there was a risk of overloading the headphones).
