i, personally, LIKE these emblems. we use them alot on Mopar Products, but haven't had a major concern with them falling off or breaking off.
when i was at the Pontiac dealership last, i did notice the '06 models have bigger, plastic (i presume) emblems on them. i think they look a little TOO BIG!!
i was intertaining the idea of removing all of them but decided against it, for now. so i think i will 'stick' with mine and hopefully they will 'stick' with ME!!!
