compact wireless - are there multiple versions ?

[majora]

hello,

how many versions do exist of the spacemouse compact ?

i had one in the past, but is was not called "compact" and i believe it had a slightly different shape.
are there only these two ?

and are there multiple versions of the wireless spacemouse too ?

thanks and greetings
