Abstract: We present the latest results from the ongoing ELM Survey, our targeted search for short-period (P < 1 d), extremely low mass white dwarf binaries. This includes the exciting discovery of a new 20 min system which constitutes a new verification binary for gravitational wave detectors operating in the mHz range. We also discuss the puzzling presence of metals in many ELM WDs. Finally, we present an updated view of the extremely low-mass white dwarf instability strip.
