Did you try the one at tun aminah, skudai? I was quoted 2.4k through phone straight, no bargain (as I knew 2.4k should be the lowest).
As my rear windscreen old tinted need to remove, they cant guarantee they wont damage the heater stripe. End up i just tint my front windscreen with them.

They are nice and use the equipment to test my VLT (around 85%) and IR (10% iinm, means 90% rejected) with old tinted.
After remove & tinted with the 3m crystalline 60 for front windscreen, they test again and I saw my VLT become just 55% and IR become just 0.2%. (means 99.8% rejected  )

Quoted just last Saturday.
First time I drive my usual speed, failed. Said no smart tag detected, and I straight stop and reverse.

Today I drive really slow, at first show no smart tag, but I just continue move forward a bit (saw other ppl comment)
At the end detected and barrier opened.
Smart tag touching windscreen.

Later I am gonna try my usual speed, but continue move forward see can or not.

Base on the quote i gotten so far their specification is on par with 3M Crystalline and Llumar Gold + Diamond 6 which are both in the 2k-2.2k range. But 3M famous with smart tag issue as its metalised firm while LLumar Diamond despite having a good TSER, the VLT is still 60+% which is a bit too bright for me.

Let us know if you finally decided on haverkamp. Would like to gather a bit more review as well.

u can negotiate
