I have the Xpel XR Plus on the windshield and sides and I can tell the difference on hot days when the car has sat in the sun or when I am driving and the ac is on how much cooler it is or how it’s not as hot as it was when in those situations. Additionally when on a long drive for Memorial Day up the I-5 to Sacramento, I didn’t feel the sun beating down on my arms like I did driving to work 20 minutes in the sun. It’s enough for me to feel like it’s worth it.
Whether it’s worth it or not for you is subject to your heat sensitivity and pocketbook. My vote in spending your money is to do it.
Maybe
@Bobby can speak to the tint he got. I believe he got something other than Xpel.
I believe
@hydbob also got something other than Xpel too.
