A friend has the factory set for his keys and I thought it looked cool. I bought three sets of these, one for my key and one for the spare key. Why the third set you ask? Well, the plastic is more brittle than the factory part, so I cracked one putting it on. Now that they are on my keys I haven't had any issues whatsoever, and they look cool. Even if I do still feel silly having a key shaped like a Panamera.
