I bought the same set, and currently have dismounted the drivers side. I was getting some wind noise and wasn't sure if it was from the deflector. While with it off, I still get some wind noise between the A pillar and the side mirror. With the deflector, it is louder, I'm going to mount it back on and live with it and turn up the radio to drown the noise.
I bought a set of these for my 2007 Prius and the rear windows really didn't fit right at all. I ended up having one fall off when it got hot one day. The front door ones fit perfectly, but they do cause some extra wind noise when driving on the highway. Hopefully the fit is better for the CT200h than it was for my Prius.
