Wind Deflectors for 2010 VFR - any good?

I was thinking about buying and installing the wind deflectors that cover the hand grips. Has anyone tried them? Do they work? Do they break easily? Are they good value?
Thanks,
J

 

Just thought I'd renew this thread to see if anyone has tried the wind deflectors.

 

My bike came with them I only use them when I know it's going to rain or when it's cold the work great they keep my hands warm and dry. I have a 5 gen but I imagine there isn't much difference in the style

 

Thanks Jerritt. That's good to know. It's a lot easier to have those than have handwarmers installed, so I think I'll go for it.
