Legit.
I was looking for someone to tint the windows on my wife's new car and found Donnie on OfferUp. Straight and to the point no bull. Tells you the prices on his card. His shop is at his place which is actually quite comfortable for a customer as you wait while he works on the window tinting. Very generous and professional. He was nice enough to demonstrate the difference from carbon and ceramic. Two thumbs up :)
