I did mine at Raytech Puchong 4 years ago.

My cousin brother then had good relations with them, so i managed to get a RM1300 tint at the price of RM900. They were also very nice, they recommended me a tint with all the concerns I had (i.e. won't get stopped by police but can block around 70% of the heat)

My car has no problems with smart tag, and is very cool when the weather outside is damn hot. Till now the screen still very clear, no bubbles or anything 😁
