For forumer sake, I need to update on my situation above.
After 1 week of usage on HO C70 tint which failed at Smart Tag lanes 90% of the time (even after changing to new Energizer batteries). I can't take it anymore and I returned to the installer, who is also as puzzled as me how come HO Ceramic Tint main selling point is for its Smart Tag/electronic friendly characteristic compared to metallic based tint such as VKool. To be fair, only Smart Tag signal was blocked, autogate/condo RFID boom gate/ Phone GPS all works fine.
I took out the HO tint after 1 week usage, though my heart ache like mad as the tint was done perfectly with good workmanship and I got use to the color hue, but had to take it out due to the inconveniences of having to wind down my car window every time I pass the toll. I went back to the installer and claim warranty, they took out the tint, and I top up money to install VKool Elite, as I don't want to take any more chances with HO tint anymore.
VKool works fine with Smart Tag now, but autogate/condo RFID signal got blocked. Well, there is no perfect world I guess. Still like the color hue of VKool, greenish, very pleasing to the eyes.
Sorry to hear of your situation. I'm also quite particular about the tint not blocking smart tag, autogate, GPS, etc. BTW, I'm also using the old version smart tag.
I wonder why your HO C70 blocked the smart tag. I've got 2 cars tinted (about 5 years ago) with HO, but using Sech 60 for the FWS. No problems with smart tag, autogate, GPS, etc.
Got another car with Raytech Ultra 70 for FWS, again no problems with smart tag, autogate, GPS, etc.
