Trouble with romeo gaskets falling out of place when changing lens,,,,,, try a small amount of washing up liquid,on the surface, its just enough to hold, an wipes away easy.
I have all three colors for replacement lenses. It is a bit trickier to change these than the juliets. That little rubber gasket always falls out when I'm trying to screw the frame back together.
Easy to replace not like the Romeo 2. But a little bit harder than the Juliets
