It comes with a receipt from the installer, not Huper Optik, but I did find the installer shop name in the Huper Optik authorised installer list.
The installer did not tint the black dotted area where the rear view mirror is. I paid RM650 for FWS only (Honda Civic FD).
I have communicated with the installer and Huper Optik HQ:
Installer: The C70 has 92% IRR rejection, chances are my front wind screen also come with certain % of Irr blockage, hence blocking completely the Smart Tag signal. He suggest me to cut a hole in the front wind screen tint, I am still considering.
Huper Optik HQ: Requested me to bring my car to their HQ in Pandan Indah for product verification and run a few test to ensure the tint is genuine. 30 mins drive from my office, I will arrange accordingly.
D newer smart tag (black color) d signal is not so strong for 3M crystalline, certain Smart Tag lane is ok , some is not.
My is the dotted spot on the windscreen was not tinted, I used my black smart tag there!
How do you know you installed genuine 3M crystalline?
1. is the 3M logo at the film itself
2. U put your car under sun, you can your windscreen purpleish.
How the above helps...
