Mine is blue and black version since I purchased it during the 1st day of the official launch date. It looks quite weird with cube mix plus.
I notice other users received silver and white keyboard version, so if you purchase now you should get that silver and white version.
Not sure why, but it should be working since the number of pin is the same and I have tested with my i7 book keyboard and it works too.
Maybe cube will only send out stocks to 3rd party sellers such as gearbest later on, as they want customers to purchase from them directly at first?
