Nice price and saving against the next best price here @Daper Almost on the hot page too....
So had the keyboard and headset delivered and it is different from the IBM type M that i normally have used.
cherry Red switches are ok and not as loud as a type M keyboard, but

The functions are as most reviews describe however. the 2 rollers can be used for scrolling on web pages or menus not just volume control, i.e. it can be assigned as mouse scroll wheel. The resolution of the wheels are ok you do need to scroll a bit to change volume and there is a lag but it is manageable. the wheels does not feel as solid as the rest of the keyboard and makes you think of a fake roller that is free wheeling and does not have a function.

You don't need the software and can do most things on the keyboard like record macros etc.

For fun i tried the keyboard on some android 10 and 7 stock os phones and amazon fire TV and the keyboard works flawlessly.
media keys, volume, roller for menus and scrolling in web pages, On the phones the usb hub also works so that you can connect the Sirius headset listen to music on the phone or use the microphone for zoom video calls. google assistant can also be used.
not tried the gamepad mode on the android phone but suspect that it might work...
Now I don't know why you would use a 200 quid keyboard on a 150 pound phone but....perhaps you can set it to rainbow cycle and use the keyboard as a Christmas star in the Christmas tree....

the headset is ok, low volume it sounds flat and cheap, if you give it some volume it sounds better.

so 260 pounds of stuff for 134 pounds that does what i want is a deal for me.
