Good review, clear and to the point.

You forgot to mention one feature of the Colibri which
might influence people's decision. The internal memory
back up battery needs to be replaced every few years
and to retain IGC approval this has to be done by the
dealer, not the owner.

That is true of almost all IGC approved Flight Recorders. The only
exception currently in production that I can think of is the EW.
