iPhone5 case - Poetic Atmosphere, Belkin Clear View or Otterbox Defender

[tech_fan]

I am trying to decide between the following 3 cases:

Poetic Atmosphere
Belkin Clear View
Otterbox Defender-tree series

But my biggest concern is the lightening adapter. Has anyone tried these with the adapter?

I use a defender case and had to file the top edges of the adaptor to get it to slide into the case. Once I did that it works perfectly.
