Break - Do not press without Fn, making the keyboard unusable. How to use the key with a drawn blue lock (on the Esc key) did not figure it out. Logically, it should be pressed together with Fn and after that all the blue buttons should be pressed without Fn, but this does not happen. If anyone knows, please write.
Included some photos to give a better sense of the product's appearance.
