3M Crystalline is a good deal since you are not worry about smart tag. Nothing much to say about 3M Crystalline, the quality is there as long as it is authentic and you have a good installer, nuff said.

If it was me, I would forgo VKOOL REM as the specs are really low.....for the price. They might have the word VKool there but it is not the premium VKool that we know (aka the 55 is great tho).

M8 is a chain shops doing all in one, polishing, tinting, etc. I prefer metallic sputter films and I believe (I might be wrong) good premium metallic sputter films requires good metal that require higher costing for quality metals and premium sputtering process. So I would only go for specialized premium metallic sputter brand like VKool (NOT REM), local branded Irispro, etc. Unfortunately as mentioned on the pricing, good metallic multi-layers sputter have higher cost thus premium pricing. I can't find any detailed info on what M8 sputters are made of tho, thus can't comment further.

Irispro Elite, I don't have the experience in this grade tho. Elite is used to be their 2nd range metallic sputter, now falling into 3rd range due to addition of highest grade silver-based Irispro Diamond X series in addition to their double sputter nano-titanium Diamond series.

I am familiar with this brand as I have posted multiple experience reviews on their DX and Diamond series (both pro and cons, installed on 3 cars) thus I would give more info on this brand here as many ppl seems to not trust local brands (not those unknown 3rd party cheap tints).

I am their guinea pig for their DX series without knowing it first and gave lots of input on that tint until they changed their product slightly and release them officially. I have both their pre-release brownish based DX tints installed along with their latest blue-purplish based DX tints installed. Both provide different vibes (earlier inside brown lighting vs current mild purplish blue), even the both lighting also I like. Excellent heat resistance (no doubt abt that, if not I would not proceed to install them on 3 cars after trying it out in one car first), premium pricing tho and a bit thick but they are the only one with HEV blue light protection thus added another layer to the tint thickness not to mentioned so many layers of metallic sputtering.

Local branded thus they pushed in the 10 year defect and performance warranty to solidify their reliability reputation and try break into the matured premium tints local market. I have solid support from Klang Valley (Puchong and Klang) branches and they will just change the tints without argument the moment any defect or installation issues are detected (no dillydally), so I love their services at least in Puchong and Klang branches.

I have preference for metallic tint as they reflect heats rather than absorb them (ceramic tints), IMO, better heat resistance in real life (but depends on premium metal and sputter process, not all metallic sputter are better, some use celup process and metal). Thus I admittedly am bias towards metallic sputter after using VKool Elite (3 cars) that lasted a decade and half each. This local brand is one of the better metallic based alternative that I can find (with layers detailed in their website) to replace my cars' VKool Elite. DX have premium pricing half or 2/3 price of the famed VKool Serendipity series (Elite).

Their 10 years warranty and no nonsense approach to replace the tints when installation issue or defect detected gives me peace of mind to go ahead with all installations. These are comments on the brand tho, not the Elite range but it is still a premium nano-titanium (titanium has no rust issues vs more conductive silver) metallic based sputter tints with additional HEV blue light protection.

My DX series on b-segment sedan with no sunroof already cost near 3K liao, so for your budget, no doubt Irispro Elite is a good deal but I am not sure what tint they use for the roof tho (silver reflection??). Are you having an EV here or cars with permanently exposed glass roof? Those roof are mostly likely already pre-tinted.

I have no experience in Totalgard Infusion pro, so no comment there.

Recently took Hamel's merdeka promo RM599 for their cheapest SILVER tint package which comes with car wash and door cup PPF. I'm surprised on their service and tint performance for the price.

Tint is only 85% IRR but feels alot better than my totally degraded 14 years LLUMAR tint which I had on my Honda City 2010 since I got the car. Did not had high expectations for its price thus I'm satisfied with the results.

I also chose JPJ compliance darkness for the whole car (70% VLT FWS and 50% VLT for the sides and rear)

Previously using 3M crystalline on my other newer cars and now I might consider Hamel's platinum tint instead for the cheaper price
