The Shop I went to was California Tint in Rosemead.
They have been in business for 10 years now.
Checked them out at BBB

Large customer basis. Always busy.
While waiting for my car to be worked on I spoke with some other customers about the shop. They had nothing but great things to say about the shop. They gave me lifetime warranty. So I have confidence in them. My GF got her car tinted there as well on her 325i. They gave her a discount because I told them I had gone there the week before.
My tint cost was $130, my GF was $110.
