So far so good.
Rides well on a Shimano 105 Di2 group set. Changes smooth and remains quiet, has not seen any rust after cleaning and going in parts of rain. Most likely given the added technology. This is reflective on price as it is almost double the price Deore M6100 series chain which came standard with the bike. Will be wanting to provide an long-term review of the longevity as based on forums and bike mechanics these top end chains should get you more kilometers. Will need to wait and see.
