Have you looked at all at the ZSA Voyager and if so, what were your thoughts? I realise it cuts down on the number of thumb buttons compared to the Moonlander but I saw quite a few Moonlander users who have used both saying they'd opt for the Voyager[0] or have got both and prefer the Voyager. Many people seem to have issues with the Moonlander's thumb cluster especially with smaller hands.
