I tinted EZTint for my front and sides, 2 layers for the sides
Initially I was using Ecotint, but wasn't happy, bubbles here and there and the rear screen had water sipping through the tint (not defaming Ecotint, just relating my experience). The tint effect also was less significant compared to the EZTint. However they did replace it for me as warrantied.
About the price, its quite subjective because my family has tinted many cars there, and also depends on your negotiating skills :D, but judging from his walk in customers, I can see that he charges relatively reasonable. For a normal sized sedan eg. Vios would be about 400+ for the whole car including windscreen.
In fact, I just sold off my car, and before I sold my car I actually went there to remove the tint. Cleaning the glass to clear off the glue was not an easy job judging from the amount of liquid cleaners he had to use, but he didn't charge me. Moreover, he was quite filled with cars at that moment, but he had the courtesy to take time off to attend to me. That says alot about his after sales service, that's why I would recommend this shop to anyone.
My car was a VW Beetle. Red colour. Maybe if you guys go there can just point out to him. The boss name is Calvin.
