We have used Safelite for years. Before that, I made the mistake of using the companies that give you $50 in cash or restaurant coupons when you get a new windshield through insurance. That glass must be much thinner because I always had cracks within a few months. Not so with Safelite.
Some recent experiences:
A year and a half ago I bought a classic Jeep. Safelite not only installed it with a new seal for cheaper than anywhere else sold just the windshield (not insurance claim), but when the trim came off they came back out to fix it quickly for no charge. I didn't have a rearview mirror at the time, but when it finally came in I just stopped in and they installed it for me in the parking lot, no charge.
Then today our rearview mirror fell off the factory OEM windshield on a different one of our cars (Arizona heat!). My wife stopped by this location and asked if they could help and in less than 15 minutes they had the car in, the mirror mounted, and back out to my wife. And this wasn't even their windshield!
They obviously care a lot about service and we will keep using them for any of our needs.
