I was using this with Apex and didn't notice any particular lag, so it works fine. You can adjust the keyboard brightness with the button in the upper right. I think the feel of the keys is a matter of preference, so please check YouTube or other sources. Before listing, I took all the keys off to clean it, and I lost the "2" key on the right side. Also, the part on the back that raises the left side of the keyboard is missing. Please purchase only if you are okay with these issues.
