when i first got my losi mini 8ight years ago, i immediately noticed a weak point (the bumper). i got this product, and since then i have slammed the car into countless objects, and every time, nothing happens except the car simply bounces off. the bumper currently has many scratches and dents in it from years of hitting many rocks and curbs, but it will not break or crack. im telling you, this bumper will last YEARS, and it will save your car for that entire time as well! for 9 bucks, i cant think of a more cost-effective upgrade to add on your losi mini 8ight. i would 100% reccomend this product to anyone who owns one of these rc cars
