If disaster strikes...
There is very little room for fingers (rather than finger nails) to get behind the modules to push them into their slots and they can be surprisingly reluctant to slide home. The upside to this is that if the worst came to the worst and you do break or over-bend a retaining clip, the SODIMM is unlikely, outside of using the mini in ultimate frisbee, to become loose or get dislodged.I was careful and broke one of mine. RAM hasn't moved so it's all good!
