Almost perfect for me. I recommend to everyone Pros below: Wireless - confident reception and fast response, suitable for games and work. Quiet enough. Holds a charge for a long time - I work a lot, without backlight, it lasts several months on one charge, with backlight - several days / weeks, depending on the brightness. Uses standard AA batteries. Adjustable backlight. Useful function keys. Very cool appearance - strict and stylish. Reliability - for several years nothing has broken. The characters on the buttons are cut out and are not erased. Has cons: A small left shift, I constantly miss, although I have been using it for several years. That's why it was necessary to insert a duplicate slash, which nafig is not needed and reduce such a frequently used key, it is not clear. I can only wish that the initiator of this idea would use such a shift all his life. There is no NumLock backlight (as I understand it, in order to save battery). It does not remember the set brightness level - when you turn it on, you have to set it or turn it off every time through the supplied software.
