Did one of those.
Ended up you have to top up for a decent product. So the coupon is just like a discount voucher.
Not much I reckoned. I paid around RM600 for a product that is supposed to worth RM1700.
I don't think that the RM1700 was the actual price anyway.
But quality-wise it is quite decent as it was installed by Solar Safe which has 5 years warranty and they claim it is a safety toni with 4mil thickness.
Thanks to all that responded. i think I'll stick to the more recognized brand like V-Kool. 3M, etc. But brand is one thing, I'm also worried of the installer as they have to pry open the doors to install the film. One pull by a not so careful installer will maybe break the plugs and give me heartache. Any recommended place around KL who knows how it properly on a BMW?
