Mine randomly spat a disc out yesterday when it was completley off.
And yep its the front foot. its too squidgy the slightest bit of pressure and it ejects the disc ive had to kind of push the fron foot back a bit.
Bit of a design flaw.
Might send it back as its done it a few times now.
The gentlest of taps underneath the eject button is more effective to eject then the actual front of it.
