ORG03X x-ring for oil shock

[Supergreg]

due to never-ending heavy rain on a (possible) beautiful sunday, I decided to upgrade my RB5 shocks with the x-rings. I put some green slime to the rings and built the shocks with care as usual.

I must say they now feel smooth as smooth can be. it feels like they have no more friction at all! but what about their sealing quality? do you guys have any long term experience with them? how do they do under dusty conditions?
