usually there is llumar logo at the rear window, Diamond 6 got 10-year warranty, tint film color green in hue, look bright, tinting shop from Llumar, and make sure it is not "Vessolar" which is their house-brand! stay at tinting shop to view when ur car is tinting.
If the tint shop wants to cheat, they will install a low grade tint for the rear windscreen with the Llumar logo. Then the side windows instead of using Llumar Diamond 6, they will use another cheapo brand with the same greenish hue.
Best way to know is to check who is the issuing party for the warranty cert and double check with Llumar that its valid for 10 years.
Many tint shops nowadays are cheating customers with Llumar and 3M products.
