Hi kawan kawan
Just to help those who are confused and unsure.
As someone had mentioned it, Smart Tag works with V-Kool. However, you will notice a slight drop in the transmit/receive signal strength maybe due to the v-kool particles and hence the gate opens a bit later when you are passing through. But it is not a problem at all as I have never been locked in the middle of the lane due to unreadable tag. It works on v-kool installed in 2001, in 2006 and in 2007 in all my cars. No issue with Smart Tag. I installed the 2001 one at v-kool HQ PJ and 2006/2007 at Tint Shop as the HQ directed me to this authorised dealer/installer. I only trust v-kool coz I am serious at cooling my car interior. Other tints might work but I don't want to risk time and money. Price - for 4 door sedan, current price - revised on 15 Jan 07 is RM2200. Expensive I would say but for me it's OK coz it lasts almost forever. Don't believe rumours, get the real facts and you can sleep well. Adios.
