Regarding issues with double clicks and backlighting: the problem is treated by installing the latest version of Razer Synapse 3.0 and restarting the computer. The keyboard does not have built-in memory, so without software it works as it wants. Summing up, I want to say that this keyboard is an excellent heir to its line. Of course, you can find opinions that earlier "the grass was greener" and the backlight shone brighter. I am personally satisfied with this keyboard, it is definitely not inferior to competitors, especially if you can get it at a discount.
