What has been the success rate of non-replacement repair of 3G windshield glass?

I got a ~0.5" "birdseye" crack after a rock came up on I95 in Baltimore. I have USAA and they use SafeLite for their repair. A non-replacement repair is free and a replacement windshield is $250 (for OEM glass). Personally I prefer the repair if possible, I've not had great luck in many cars in getting the windshield glass installed properly and leak-proof.

 

I also have USAA and used a Safelite shop. They fixed the crack fine. It was a pretty good starburst. You can still see the mark, but the guy said the crack shouldn't spread. Like you said, the repair is free, which is the best part.

 

Thanks, makes me feel better as my TL goes in tomorrow morning for the repair.
