I30 weathershields aftermarket?

Picked up my stonking new i30SR today :laugh: But I had to be stingy with the additions because, budget...

I want weathershields but didn’t want to pay dealership markups on things like those and a boot sill.

I saw some on that website that starts with E and rhymes with Pay. They stick on with 3M stickers (presumably heavy duty outdoor), would these be worth it to put on myself? Or waste of money and they’d fall off in a parrot’s fart wind?

Thanks in advance!
