Difficult to mount
The quality of the shield itself is good: very clear, little if any perceived distortion, good up/down operation. HOWEVER, it was a real chore to exchange the old shield with the new. This, of course, is an indictment of the HJC helmet itself, not the shield. The task is nothing like it is on my Shoei helmet -- out with the old, in with the new in less than a minute, which is very convenient when conditions (e.g., weather, daylight) change.
When it's time to replace your HJC shield, you might consider applying the $ towards a helmet upgrade.
The service from motosport, of course, was first rate.
