I'm currently using the RK61 as my first mechanical keyboard (needed one that was wireless). Ordered a Keychron to replace it for a few reasons: arrow keys block the /? key (you can switch with Fn+Enter or just use Fn but it's clunky), software is hard to find, had to get the right version from a random Google Drive and it's not very customisable (can't change Fn layers, combos etc), battery life is a bit meh (two days or so), and I miss the function keys (for programming, etc.) Just some things to consider if you're thinking of buying and are new to these types of keyboards.
