This was the third vehicle I have taken here to get tinted. I obviously haven't had an issue, because I keep returning. They are very professional and treat you like an individual, not just a dollar sign. You are welcome to drop off your car and head out, or stay there, but bring your own form of entertainment if you stay, the 1980's TV set might not entertain you too much. As for the Groupon, they will usually have a deal in-shop that will meet or beat the Groupon offer. And make sure you choose the correct Groupon option, as the two small windows in the back seats aren't included as freebies, they too count as windows. When the service is completed, they will pull the vehicle up front for you and have the keys ready for you to pick up. They give great information on maintenance after installation and upkeep down the road. I highly recommend this location for all of your window tinting needs. And everytime you bring in a vehicle after the first one, you get additional savings.
