Imagine my disappointment when I get this replacement keyboard and after installing it I realize that even though it fits fine and works correctly, it has a serious defect. All the keys that have alternate functions by holding down the Function key(FN), like turning the volume up and down. increasing or decreasing the brightness or turning the WiFi on or off are printed so faintly that they are almost impossible to see. Even the the Function key itself is almost invisible. I have attached pictures so you can see(or not see) what I am talking about. What is really sad, when I contact the company about the problem asking for a replacement, they tell me that all the keyboards they have in stock are defective and my only option is return the keyboard. I would not recommend you order this keyboard from this company as I suspect you will get one of the defective keyboards.
