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.

I personally installed the color stable series product code CS3090 and antifade series just for my masterbedroom. Color series price is slightly cheaper than antifade series. But the function of antifade lagi bagus, because it has 100% ultraviolet function and the TSER percentage also very high. Do look into these 3 function on the film tinted which is Infra ray (Heat), Ultraviolet rejection and TSER function. These are the 3 main function to look into, another than that is for pattern saja.

I can suggest all your bedroom put the AntiFade series tinted film. It can block the sun heat in the morning and let you sleep chilling till 10am above. Haha!! The antifade series product code will be AF2090 high spec or AF3060 lower spec.

Your welcome. Hope my comment can contribute on your decision making journey. =)
