Tint Shopping...seeking advice...please help!

I prefer not to go to tint star, i had a bad experience with them the first time and it got me to the point of no return. I know alot of people say they have gone there and have had good experiences but maybe i was just unlucky but i WON’T go back there. I don’t mean to bash the guys work or anything but its just a personal thing. Im wondering if anyone has used Ziebarts or Showroom Car Care, and how they like their work.
