Works awesome with Shimano 12 speed

I've used it once or twice and have initial impressions

Time to change the bike chain and decided to go with this KMC XI2 chain. It is advertised to work with any Shimano or SRAM 12 speed and it really does. I have a Shimano 12 speed drivetrain and works flawlessly at this moment, I haven't had any issues whatsoever, no strange noises either, all shifting is very smooth and precise, I definitely recommend this chain to anyone for their 12 speed systems.
