The photosync TSER numbers are impressive, but you do pay for it.
I ended up going with the Suntek CIR (50% front, 30% rear). Quality install, no issue there, but I was a bit disappointed by the haze when the sun hits it at an angle. Was told this is 'normal' for most ceramic tints, but will definitely take some getting used to.
Anyone know what tech photosync uses? Is it also ceramic?
