stupid shit my smart tag can't use. now everytime need wind down windows. shit

Yup, same thing here. Bought highest range (u70 and centurion Rx), total 3k. But park under hot a while, the car become microwave d. Not sure how is other brand performance, so I can't really bash raytech.

But i am disappointed with the performance

same also...feel like kena scam by raytech. dammed hot leh the car park under sun after 30 minute.
worst is that i still feel burning sensation from side window .

end up..... feelling angry for wasting money neh. Performance wise, same as those tinted shop class B tinted rm500.
last month buka buang (very sakit hati) and up tint vkool elite.....now i am happy user.

/k expected ice cream in car to not melt with 3k tint

Well,building tint...cheap big good ...can last up to 10-15 years.you don't feel the heat at all for 1 hours ...just warm jer...how I know ,because my ex wira use building tint.

As for my current vkool elite...at least 2 times better than stupid raytech.park 45 minutes under bright hot sun....the dashboard just feel hot yet able to put your hand on top of it.

You pay premium,but get lousy quality tint ...how would you feel .the quality is same par as those rm4xx no brand tint.
