Mine took almost three weeks. Was sat in customs for days and then out for delivery for three days because my address was labelled incorrectly.

I just got a Q5 Pro myself and use the End key all the time so I reworked the keys and flashed the firmware.

[del] is now [PrnScn]

[pgup] is [del] / [insert] (Using + [fn] key)

[pgdn] is [home] / [pgup]

[home] is [end] / [pgdn]

I’ll have to order new keycaps to match, but so far it’s felt good to use that way and I find that the only time I mispress is when I look at the keyboard.
