Got the Groupon for my Mom. $90 for 5 windows on her old Range Rover. There are a total of 7 windows that need tint. Groupon listing states "Lifetime Warranty." She shows up on time for the appointment and has to wait for 20 mins. During the consult, the tech is busy answering the phones and talking to the people calling instead of taking care of the customers he has standing in front him. We knew about the extra windows and that there would be an additional charge for them. They wanted an additional $90 for 2 tiny vent windows and 2 windows in the back that were no bigger than than the door, side windows.
After the upsell spiel, we were told that the Groupon tint only has a one year warranty and the tint probably won't last that long.
DO NOT waste your time with these people. Horrible customer service and dishonest business practices.
