RB450G: how should I insert microSD???

This is really stupid question, but I can not help myself, I must ask:

How in the heavens name should I insert microSD card into RB450G? I know slot is on back side, but somehow microsd card does not fit! I can insert it for just about 2 milimeters deep, and it is not locked/latched. See the picture below: is THIS normal? It does not go any deeper…

This looks good, no problem

It is standard size of microSD? http://simple.wikipedia.org/wiki/MicroSD
