Expensive due to purchasing from US for AUS (my choice).
Near same tint as OEM which was my preference. Therefore, the difference is only the more pronounced bubble. This is still aesthetically matching to the bike; looks great!
The change to wind diversion is noticeable and effective at freeway/motorway cruising. The wind noise is lowered and less buffering. I notice the diversion from screen to only the top of my helmet (depending on riding position. You now hear lower, deeper frequencies from your bike.
Using Shoei Helmet.
Misleading decals on front of screen - No R1400 or bikes branding.
More time/testing required.
