The mini is a waste of money for what it's worth. Sure, some users of the item may not end up using all 15 keys immediately, but there has been incredible enhancements to the software since it was released. The large deck could see a decent discount of at least 20% which is plenty for most creators.
I have both for different reasons and I think the mini is better for smaller things but if you need macros for editing or something along those lines, just get another keyboard. This is kind of a waste is you don't intend on using it everyday and if you have more then 10 macros then it's not really worth all of the setup. Would recommend if you need it for something like streaming or for macros that you would need in the moment, other wise it's too much money for something you could just program on a keyboard...
