The aluminum cases bend if you apply too much stress to them. But you just bend them back and all is fine.
When I was fairly new to riding with my aluminum side cases, I was lane splitting between a stopped large truck and some SUV with a mirror that stuck out way too far and managed to catch a rear tire on the big truck by an inch or two while trying to avoid that big mirror. I went from 5 mph to 0 in about an inch. It bent the inside of the case out a little bit when it absorbed that energy. When I got home, I spent a couple of minutes with a rubber hammer and now you can't tell which case got bent slightly.
I like the toughness of the Touratechs.
