The properties of superfluid He-3 in the regime of negligible normal fluid density is both of fundamental interest and yet very simple. The behaviour is dominated by the properties of the condensate, and several phenomena, other-wise masked by the normal fluid, become observable. We discuss the techniques needed to cool the superfluid to T much less than 0.1 T-c. We discuss some examples of the unique low temperature behaviour; quasi-persistent spin precession, possible orbital precession, imaging turbulence, nucleation and the phase diagram in aerogel.
