I used their website (mobile friendly) to book an appointment. The service was fulfilled by Safelite's mobile unit out of Fairless Hills PA - and my technician was Matt. I received numerous texts regarding the appointment, and progress regarding Matt's expected arrival time. Once he was there, it took him a bit over an hour to do the replacement.
The workmanship and quality of the repair was excellent. Pricing was fair, particularly considering the high quality of work and customer service.
A few additional facts: for mobile service, you can pay a nominal amount to reserve "first appointment" and avoid the uncertainty of a 4 hour time window. Second, for a nominal fee, Safelite can also replace your windshield wipers. Third, they are able to seamlessly transfer your inspection sticker from the old windshield to the new.
