Came in with an appointment on Saturday morning and selected my tint and was told about an hour to two hours for them to finish. The whole process took approximately 3 hours to get done and that was mostly because they had a lot of customers that came in and they quickly filled up and got behind which I understand.
The customer waiting area actually made the 3 hours go by quickly, they have two large comfortable couches and they gave me the remote and let me choose what I wanted to watch, along with offering me soda or coffee as well. Even though they took longer than expected I will definitely come back and if you make sure you go early to get your car done quicker.
