Personally, I do not think these are worth it. I bought a set to go around the rear fog light reflectors and the amount of dirt that gets behind these sort of products is insane. After just 3 months, I took them off and it was affecting the clearcoat. I stopped using them. The only products I use that cover up stuff on the outside of the car are my CF mirror and camera covers. The mirror caps completely cover and don't allow dirt underneath to effect the paint and the camera covers cover plastic, so not an issue.
Just my .02 cents on the topic. If you have PPF covering your entire front end, then this won't be an issue. If you don't, then I would seriously consider not putting something like this one.
