1. Did exactly what it's supposed to do
Highly highly recommend the aluminum pucks!
Had a low slide in the rain on the race track at around 40 mpg. Bike sled on the pavement. Not a scratch on the side fairing. To give you some perspective the tank cover had a small nick. The clip on was bent downwards and the tail is grind down. Even my Gilles HP rearset was bent. But still there was not a scratch on the side fairing. The engine bolt was only slightly bent and the the slider was grind down about a quarter inch.
Only gripe is that they stopped making the brushed aluminum one. I prefer aluminum since if you tip the bike over the scratch won't show as much. But all I needed to do to get rid of the anodized color is to drop the puck in some rust remover. The color was gone in 5 minutes.
