If you know their profile, you should expect that they are fragile. They are. You have to be careful with them. They fall apart easily if you handle them roughly. The only way to avoid this is to make them out of metal and they will be more expensive. One I broke once or twice for being too aggressive with it. Easy to assemble rear panel. I think they are beautiful because they are hardly noticeable. I know they are fragile due to their nature but I have been using them for over 8 months now and they are still in perfect shape. The stickiness also holds up well.
