Yeah I have the rubber and plastic separation problem. I hike and camp with the camper a lot and i carry it outside a bag all the time (should slinged, strap mounted with a Peak Performance Capture Clip, etc) and it get bashed around quite a bit... The extended eye cup is great but eventually the part where the rubber is held down by the plastic breaks due to stress and pulling forces. Result? Super gluing everywhere that the rubber touches the plastic frame does a much better job of binding the rubber to the plastic than the initial rubber and plastic tabs does. Now it's much more robust and working great!
