Fellow at work told me a bug deflector can help save my windshield. What does anyone think?
I think the fellow at work is correct. The bug deflector can change the path of a rock that happens to hit it.
Unfortunately, most rocks approach the windshield from above the height of the common bug deflector.
did not help mine at all. first window 2 repairs then a few weeks ago a truck kicked up a large UFO totaled the window. I would say that the deflector has saved the leading edge of the hood from chips.
We lost 2 windshields to getting pinged on the bottom edge under the wipers from rocks bouncing off the hood. Since installing the bug deflector that has stopped however, it doesn't stop bugs and rocks higher up.

IMHO, there is actually no way of telling whether a bug deflector has saved your window or not - without doing some sort of "mythbusters" testing. I would imagine that it would have an effect on the wind pattern across the hood, so there is a possibility that it might have some sort of beneficial or even negative effect.
at 200mph it may well create enough force to direct the air up enough to matter(though i think mine would not stay on the jeep at 200mph). BUT does it really matter if it hit low, middle or top? once its broke its broke. If they ever stop free replacement on full coverage i will install a polycarbonate/ lexan type front , the one in that thread that went TROLL. I do not have a inspection here. I can run what ever i want, from the motor to the lack of fenders etc.. AZ no gun permits for open or concealed. Its your choice and its your rights.
But the UFO that hit me would have not damaged the new plastic windows. Mt window put glass on my lap the object made a 3/8 hole THROUGH the window. Then i had to wheel all day with that, what a world.....
If anything it saves your windshield from pitting of smaller debris. Other than that, they are useless... Won't stop anything that that will cause chipping.
My proof? Mind you it isn't a Jeep but my brothers both have the same truck. 2006 Dodge Rams... One has a bug shield, the other doesn't... One brother has a bunch of pitting in his window while the other doesn't... Both factory glass (as they bought the trucks new), both drive the same distance each day in the same conditions because they live near each other as well as work at the same place, etc, etc...
HOWEVER, with the bug guard, there is still the top 1/4 or so that still gets minor pitting while the one without has the whole thing pitted. No chips for either of them though and I don't attribute that to the bug shield because my father who ALSO has the same truck as my brothers, gets a new windshield every year due to rock chips as well as having a bug guard on...
