Review on Zanch Window Tint Tools Vinyl Wrap Kit for Corner Shower, Car, and Household: Shank Card, Felt Squeegee, Razor Scraper, Cutter Knife - Easy PPF & Glass Protective Film Installation Solution by Keith Leach

The set was very cheap, I mean very very cheap, so I figured it wouldn't work. Well, the tools came with no instructions on what each tool is for. So if you're starting out, good luck. And two knives were garbage. So all I've heard is that you need stainless steel blades to avoid scratching glass and easily cut tints or vinyl. Not to mention that low cost is cheap crap. I think I've learned that I won't be looking here for better tools as much in the future.
