This stuff is awesome!
I love this stuff. Especially for those of us living in an apartment or some form of "temporary house" where replacing the window with something else isn't worth it. Benefits.

water on it (just to make sure it's a damp surface), apply the film, straighten, work out the bubbles. Hands down the biggest challenge is getting it straight, and cutting it straight.

Insulation it does help a bit, but not a tone. We put this all over our biggest window (the South patio window) in our apartment and that window gets sun all day. I would say it knocked maybe 5-10$ off of our monthly power/gas bill (depending on season). Not much, but after a few months, easily paid for itself.
Note this stuff is pretty thick, like a sheet of rubber. Not thin like the wrap you put on a plate of food. That helps insulation, installation, as well as removing it, rerolling it so you can take it with you to your next place.
Strongly recommend this to everyone, but even more so to those living in a more "temporary home".
