You don't have to do anything but use it. The battery never goes dead. just room light is all it needs to charge. The best keyboard I ever had.
I got these replacements for some basic Logitech keyboards that were getting long in the tooth. I have a couple of Razors and like them well enough, but the software drives me nuts. These fit the bill nicely. They are metal and have some weight to them, which is a plus for me. The RGB is ok, but I haven't played with it too much. This is my daughter's setup, and I will let her change it as she wants. Keys are sold and are not quite as "clicky" as I thought they would be, but that is fine with me. It is big enough to feel comfortable while typing but small enough to save space. Overall, I am very happy with this purchase.
Typical Logitech quality. Solid construction, good typing, dimmable lights, some gimmicky light pattern options, looks sleek, open space around the switches / keys so it will be easy to clean.
-Software is easy to use and useful. -Solid feel to the keyboard. -long battery life/easy to charge -neat extra controls.
