So far we've had three cars tinted by Specialist. We've been very happy with their service. Because I like to "inspect" things, I was able to see a few tiny bubbles on the window. We never returned it because I didn't think think would affect it; it hasn't yet. We would have loved to go with the Limo Tint since it gets very hot in Tucson in the summer, but we were also afraid of different state laws--- in some states you cannot have limo tint. If you intend on staying in Tucson for awhile and have people riding in the back seat, I would recommend getting their Limo Tint. Because we didn't, we sometimes have to place extra sunshades to prevent fading of the seats and plastic in the car. We also sometimes put extra screen on the windows while driving.
The tinting itself does not take long at the Specialist... but the wait may be long if there are many people ahead of you. Call ahead and make an appointment.
