I had a rock strike my windshield on my new Jeep on the 215 a couple days ago, and of course a chip and star started.
I immediately called Safelite to try to fix it before it spread.
I chose a mobile service repair and it was fixed the next day. The tech was prompt, friendly and texted me a couple of times about the arrival time for the repair.
The star is gone and there remains only the very slightest visible pinprick like spot.
I recommend this company and service.
