I have done with IrisPro here. Good quality and price is reasonable compare to 3M. On my side, i wouldn't compare vkool with 3M and IrisPro, because 3M and IrisPro ( in my point of view ) is consider atas brand, LOL.

What I want to give feedback is the after effect for IrisPro tinted. The weather at my house area is very sunny, when it shine onto my house, honestly speaking I do not feel the heat impact from the glass panel. I can just open my ceiling fan in the middle of hot evening is sufficient enough. Of course when the sunshine hit on top of your house, you will feel slight heat coming from the bumbung when you had your nap time in the evening.

Overall, I can say quality product come with a price, you will be happy to enjoy the after effect. Besides I did my whole house for a very minimal cost and squeeze the vendor abit.
