If quality of both tints are on par, do take the TSER difference with a pinch of salt. We are not even sure how each brand calculate their TSER. IMO, I don't even think they use same formula to calculate them.
Does Hamel Platinum truly have much higher TSER than Irispro Elite?
Becoz I saw in their website (no detail specs), their listed TSER range from 63 to 77. Did not mentioned the VLT, but at the same screen uses 50, 15 and 5 VLT pic. So I am assuming that it might mean that TSER 63 refers to 50%VLT and TSER77 refers to 5% VLT. Just a guess work as I might miss seeing the full specs of their platinum series.
If above is correct, then Elite 50VLT has TSER of 67 and 5VLT has TSER of 85. That should be higher than hamel if you just want to compare paper specs.
However as mentioned I would take the TSER as an initial guideline only. It likely won't be an apple to apple comparison. So if reading a near a similar range, just treat them the same (for branded tints, no name brand can listed sky high TSER but likely can't really back it up long term).
I still feel VKool Elite TSER 55 seems to worked more effectively than others that listed 60++ at 70VLT. So my bias of high quality metallic sputters vs nano-ceramic (just my preference due to metallic has better heat reflection differs than that of ceramic absorbation properties.
As for JPJ summon warranty, I think I saw in website that the warranty apply if you follow using JPJ compliant tint....but then if choose JPJ compliant specs.....then what is there to summon? Mmmm. Maybe in reality, they just cover all JPJ summons regardless of tints compliancy? Some brands do that.
"The only difference is that the Batman series is still JPJ compliant even if you wish not to follow the regular JPJ compliance stated by JPJ. The JPJ compliance is in terms of VLT is 70% for the front windscreen, 50% for the 2 driver's side windows and 0% for rear side windows plus the rear windscreen. So, with the Batman series package you can choose not to follow the JPJ compliance but your car is still JPJ compliance. But with the Hamel Signature package you need to follow the regular JPJ compliance in order for your car to be JPJ compliant."
TLDR: They insure the illegal tint by covering your summons, going above JPJ VLT limit is not JPJ compliant in any sense of the word
