Very protective shell but not compatible with the magnetic Dock Sony DK31

I hesitated to return the 2 that I acquired on this site for my 2 x Z1 as incompatible with the special adapter boxes of Sony DK31 Magnetic Dock while it was said when I bought. Too thick, and must décoquer connect on std adapter, or should the plane .... Same also for Muvit minigel asquises on another site and I returned them for exchange. Only Krussel for Z1, a little more expensive, but much more aesthetic and fine, just go with the Dock DK31 adapter.
For all the cited cases against going with the USB cable Sony magnetic proposed separately without Dock. So I kept the 2 x Mumbi purchased on this site backup because cheap and cost me almost as much return. I'm just very disappointed that this site has posted a lie, since fortunately corrected. So they will not see me and I do not recommend it.
