Wiper blades question

I have a 2011 X3 35i, and need to replace the blades. Does the Bosch ICON fit?I know left side is 26" and passenger side is 20". It looks like a better blade over the Bosch evolution. I live in Canada so I was just going off what Canadian Tire has.



Also, which one fits the back window blade?



Does Costco have blades that fit the X3 like the Michelin blades? (if so which model)



Also if anyone has a vid on how to detach the blades to replace them. Thanks,
