I had 3M tint on my Prime. And it looked great, but I noticed that I was always feeling the sun on my arms and I never felt the sun on my arms and face while driving my older prius. I then realized my older prius had Crystaline or Ceramic tint which, while more expensive blocks not only the UV rays but 60% of the heat from the sun. So I went today and upgraded to the Dub Series Ceramic Tint and man alive what a difference. It was like driving around in a refrigerator today! If anyone is debating going for tint for their Prime, I highly recommend spending a bit extra to get the 3 Dub, Cyrstaline, or Ceramic type tint. A million times better in terms of comfort in the car. And if you are in SoCal, I can't say enough great things about WINDOW TINTS GLENDALE on Brand Ave. 709 S Brand to be exact. Amazing staff and amazing work. And no, they didn't pay me to write this haha.
