I'd like to install some window film to protect my furniture and rugs from UV light and keep the apartment cooler, while still allowing a good amount of light through for my houseplants. I was told that 3M Prestige 70 would be a good choice for this. I've been unable to find this product online for sale. All I find are companies that will only sell it if you pay for installation as well, which gets ridiculously expensive. I can definitely make this a DIY project. I went on Amazon and found this stuff:

WINDOW FILM

Seems to have the same specs as the Prestige 70. But is it a quality product? Or is it something made in China that won't do what it claims to do? Anyone have any experience with this? Or perhaps know of an affordable source for authentic 3M window film? TIA!
