I'd like to know how well it works, too.
I'm really happy with the moon roof deflector. With it in place and the moon roof open at 65-70 mph I can easily carry on a conversation and hear the other person. It is a very noticeable difference on the CX-5. On our 3 it was an improvement but it wasn't as loud to begin with so it wasn't as drastic of a difference. If it is really gusty out then you'll still get a fair amount of wind noise but if the wind isn't bad it is pretty quiet.
With the visor in place it is actually quieter to have the entire moon roof open rather than just the back lifted up on it.
I drive with the moon roof open now just about all the time, unless it is raining or too hot. It is a great way to get fresh air through without getting blasted like with the windows down. Then if I want a bit more fresh air I just crack the right rear window an inch or so and it will sweep through the cabin quite well.
I'll even leave it open when it is lightly raining sometimes if I'm moving fast enough for the rain to just get swept over the moon roof. The only problem there is if you slow down any water that is on the roof will move forward and into the opening.
On our last car I rarely ever used the moon roof until we added a visor to it. Then we used it so much it became an item we actually looked for on the new cars.
