Great microphone but terrible battery life.

Overall works really well, easy to set up and flawless receptions, really makes a big difference for recording lectures. The big problem is battery life, brand new Alkaline batteries will last 70-90 minutes which means you must change batteries before every 1 hour recording session. Gets a bit expensive and there is no way to know how much microphone time remains. A dead receiver or microphone will result in no sound being recorded at all.
