How do the switches on the keyboard sound? => I have a Vortex Pok3r with MX Blue - no comparison, but "man" gets used to it.
How long does the battery last? I can't say the exact runtime, but it's quite long.

Sound: Discreet, pleasant
Battery: Feels good, does not need to be charged so often; is charged quite quickly

The "flat" keys and the short stroke take some getting used to.
I found the Logitech G Pro better; unfortunately there was no Swiss keyboard layout, so I got rid of it :(

Sound good, not too loud if that's what you mean.
Battery is also great I can't tell you the exact runtime but I don't have to charge it often.
Not really good answers but better than nothing.
