I have this film on my stairs, it cuts easily on false-curved etc. Of course, after 2-3 years where it touches the foot and especially if you wear boots or half-boots at that point, the design "comes off" a little, but it is not something visually annoying. If it shows serious signs of wear at some point, I will put the same one again, far better than some chrome-plated stairs of commerce where they scratched easily and looked very bad afterwards.

Particularly fake. The glue is not good at all. It definitely needs support with screws. It cuts with the slightest touch. It requires caution.

I do not recommend it, very fragile construction. It broke with the slightest touch, I bought a second one and it also broke, so I had to put blades and support it

Fake thing, wasted money.
The product was purchased and installed correctly.
Where the bumper made a corner, the spoiler was ready to be cut...
The screws from the set were inserted and on the first ride it flew off on Peiraios Street at 100km/h...
Only the screws and some material that had remained on the screws remained on the bumper, wasted money and wasted the bumper.
