I got the large Cuppini screen mainly for my hands. As others have mentioned the wind really chills the hands.
The screen did a really good job for the hands. Otherwise I hated the look, and I found that at night the two layers of glare (windscreen plus visor) sometimes made seeing things a problem and rain was a challenge as well.
One thing I didn't expect was backdraft. I wasn't getting wind from the front, rather a draft on my back. At the end of a commute in the rain, the back of my jacket was like the rear window of an SUV: filthy.
I cut the screen down to mid height and liked the look, solved the glare, solved the backdraft, but got a lot of turbulence with painful noise in my helmet.
I cut it down to fly screen height and now I'm happy. I still get protection for my hands, like the look, and no drawbacks.
For those thinking of cutting screens, I know there are how to's out there but I took it to a local glass shop after I found out that's where the local motorsports dealer had screens cut. Very happy with their work.
