All posts under same 2018 thread, still very valid.
In conclusion, V-Kool = Very Good in Heat Rejection. But MIGHT have Smart Tag / GPS / Autogate issue, depend on your luck.

Smart tag signal reduced, need to be pass very slow. Autogate/Gatepass signal also will reduced significantly. GPS lagi teruk to the point it is unusable unless you put your phone directly under the windscreen and touching the windscreen for almost full signal.

If you need GPS navigation, stay away from VKool. It may be the best, but it is fundamentally flawed for GPS or radio signal usage. It may also affects RFID in the future.

I am using VKool Elite and I quite regret my decision in listening to the salesman, three times, three different cars, at three different times. No improvement at all to GPS, autogate and smart tag.

If you go for Huper Optik or 3M Crystalline, you can cut a hole for the Smart Tag (Smart Tag is using infra-red signal, not radio wave), or stick your smart tag at the black dotted area behind your rear view mirror. Usually they won't tint there. The black dotted area also camouflage the smart tag so it is not that visible when looking from outside the car.

My advice, stay away from VKool if you need to use your GPS to navigate around. SmartTag is okay but need to drive very slow to pass through, but gatepass can't use and autogate remote reduced. Alternatively on the expensive side of tint, perhaps 3M Crystalline. Or mid range, Llumar, Hamel, etc.

Salesman will sure say improve la, GPS no problem la, gatepass no problem la, just to secure sales (usual salesman talk la, which salesman will say their product is bad? Don't get misled.). After pasang, no improvement. Don't believe the VKool salesman.

Eh ~ sure that wrap Smart Tag method work or not oh?
Sound a bit not so scientific, lol.

Why not try other brands?
But each big brands have their own issues la.

3M = Crystaline 70 not Smart Tag compliant

Huper Optik = Heat Resistance not good

Llumar = Heat Resistance not good (but only few users are saying no good, really few, if compared to other brands)

Else say Llumar heat resistance satisfied. Heat rejection is really personal i think. Where u park, when u drive, etc.

So for me, if i wanna go for big brands, I might try Llumar la. Since lesser complaint.
But in real life, my budget allow me to go for Raytech mid lower spec only 
Even review toward Raytech is fifty fifty only, some very satisfied, some not really toward the heat resistant ~

Other Brands
Didn't survey further on other brands like Haverkamp, Glastec, Irispro because too far from my home.
But overall review for these brand seems not bad. You may further research la ~

For me, VKool doesn't justify the price la. Charge most expensive price in the market, but need to depend luck or with so much limitation to have GPS / Smart Tag / Auto Gate working.
Need to slow down, need to change to UHF, in-built GPS cannot use, etc.

For testing purposes, ask them to demonstrate to you, and go to your house and test the remote/gate pass/smart tag/GPS Waze Google Maps. If you feel okay with that tint, then okay. If they don't want to do it, then they have something to hide.

As for testing on GPS or Smart Tag, you can request staff car
As for testing AutoGate/Access Card you could ask JMB. I am sure that they will have some feedback from V-Kool users

By the way, try not to use metal cover for your phone as well

And is staff car available at your dealers to test?

Autogate/Access Card is not working with cars using VKool tint, only causing more inconvenience for those who use this tint. Tried at several locations, other ceramic based tint have no issue at all. The only issue is Smart tag non detection but that is with 3M Crystalline tints.

Even with bare phone without cover also same thing, very bad GPS signal causing Waze/Google Maps to jump around or couldn't get accurate location.

VKool is just a tint which cause more inconvenience and it outweighs the benefit and cost.

Just wish to share my experience of using it. My advice is to stay away from metallic tints.
Try it with a car with VKool tint. As I mention, you put your smart tag/phone directly under the windscreen (in some cases touching the edges/windscreen) then it will work fine. 2 inch further than that, you will see signal reduced, hence inaccurate GPS/Waze/Google Maps and slow detection of smart tag. If you wrap the film around your smarttag/phone, it would be the same as the cases I mentioned before, placed directly under and touching the windscreen. If you can live with it and doesn't cause any inconvenience to you, then you can consider VKool. Just to share my words of caution before you commit to it and expect signal degradation if you use VKool.
Joint Management Body.

If you live in areas with autogate such as office building car park, gated community houses or condominiums, you will be given a card/tag which will be scanned from a distance without the needs to wind down the window, and the gate will open for you to enter/exit. Such system are installed by developer during construction and managed by JMB.

Regarding new tint rules,the paid 5k type front windscreen Max tint is how many % ? Sifu.

I have been using Vkool Elite/REM40 for almost 4 months; no GPS issue from landed, parking lot (underground), and no issues with automatic gate

No issues with SmartTag either

But now I am using RFID already

So far so good, smart tag OK, auto gate remote sometimes got to go nearer to my house and GPS is ok too.

You can take Vkool Rem40 + Vkool elites tho.

Hi,

We all know US tinted film was good. But must be original version.

Do you guy want to try Europe spec tinted film? My friend who operate his own car accessory in Johor Bahru, Kempas did get those so call Europe spec tinted film in on next month. I will get a try and update soon. According to him, pricing was cheaper then 3M and V-kool.

Saw one x70 owner bought the tint from AliExpress. Spec wise was great, irr 98% tser 70%. Cost him rm1k, send to installation outside cost him 300.

Seem like this is a good practice to get best bang for money

Do you know the Vkool Elite's TSER? Is the Vkool Elite the best heat rejection tint with VLT>70% that is JPJ-compliant?

Also, is V kool30 the darkest tint with highest heat rejection in the Vkool line? Is there a Vkool tint with VLT 20% or 10%?
