I've had one for a few weeks on my bike, very pleased with the protection, only get the top of my shoulders and helmet wet under hard rain.
If I get rid of it it was only because of the noise. I'm 6.2ft, and the wind blows awfully right in my helmet visor, as loud as it feels like having a vacuum inside.
That was really the only problem with it. I've ridden maybe 20 diferent faired bikes, absolutly none gave a better wind and rain protection (even the RT).
Of course, if you stop under rain, you get soaked...
