I got my "Coral" cap direct from Dwarf Factory so I received it a little while ago. I think it looks good, although it is true that the SA version makes it somewhat more difficult to see what's inside without distortion. I did have to add a little tape over my switch since the cap felt a bit loose to me, but after that it has been fine.
LittleKaijuSA R1 & DOM have same height, the only difference is that SA top is concave while DOM top is round. DOM profile zoom-in the detail and showing off keycap content better.
