Huper Optik C70 Review:
I just installed HO C70 for my Front wind screen as the old one was removed when I replaced my windscreen. Previously using VKool Elite and all thensode windows are now still using VKool Elite that is already 7 years old. VKool Elite still good and reject heat very well, no discolouration what so ever.
As for HO C70, after 2 days of using and passing 8 toll plazas, initially for the few toll plaza the Smart Tag works, though a bit slowly, but after that it just stopped working under the C70 HO tint, battery life of my Smart Tag still good, so now I have to wind down window and hold up the Smart Tag to make it work. Was really surprised as the reason I opted for HO is for their Ceramic tint which say to work well with Smart Tag, but it’s not the case. Really inconvenient. Even the installer had slight doubt before installing, he told me errrr...HO has upgraded their tint and might not work well with Smart Tag. Too late now.
As for heat rejection, VKool definitely is better and the vision is also clearer compared to HO.
To whoever wanted to install HO C70 for FWS, take note and think twice.
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.
