I have now used Vegas Auto Glass 2x and had a fantastic experience both times.
The first time, they came out to my office to replace my boss' windshield. They came out the day after I called them, did the replacement very quickly, and charged a very competitive rate.
The next time I used them, I called the day the rock chip happened to my windshield (a Thursday) and the owner personally came to my home to fix it on Saturday evening. Only a $10 charge because they were able to bill my insurance.
Some of the best customer service I have experienced in Vegas. I recommend to anyone in need of a quick rock trip repair or any other Auto Glass needs.
