Does bug deflector on cx-5 work?

[CX5BC]

Hi,

I am wondering for those few that have installed bug deflector on cx-5, will this work to reduce rock and bug splatters on front wind shield? I am not talking about mazda oem hood guard.

Please share your experience. (Or any similar suv)
How much will the deflector reduce highway mpg?

Thanks
