no one talk about ecotint.... 

my opinion, brand is one thing...but installation skills/intallation room must be pro too.
if not end up a non happy cust with bad review.
later people come say dat cust is using in house brand or fake products.
paying thousands of ringgit and end up with lousy result is not a good practice.

Have you check out HUPER OPTIC. Extremely good tint.
