Just a bomb keyboard. Excellent stuff. I bought myself and the whole family a keyboard. Mine survived a spill of coffee. But Logitech technical support, as always, eats feces. When you ask them what material is better to use for washing keycaps and switches, they write that spilling liquid is not a warranty case and send it with a forest. I hope Logitech support will be taught new scripts, because it is dull and absolutely not loyal. And their products are great.
