Okay, so where is the "add to cart" for the "STRAFE/K65/K70 LUX" key cap set? All I get is "find a retailer". I've had this keyboard a little over 2 months and I have a broken DELETE key. No rhyme or reason. Just broken. I take very good care of my stuff. This is unacceptable. Please provide a proper link so I can order replacement keys.
