Just found the one you mentioned https://www.amazon.co.uk/Mionix-Avio.../dp/B00HGKOD9G so your sole reason for picking it is how it looks since it doesn't look like a robotic fetus as you put it ?
I was reading the reviews of it as well and I can't really see anything that sways it to be super good or super bad so to me that makes it seem like an average sorta mouse really.
