Excellent item. Records about 125 seconds audio. Bigger the speaker, better and louder the sound. 8ohm 1.5 inch speaker is enough, but amazing sound with 4 ohm 5 watt 4 inch speaker. Quiescent current from 18650 battery is 3.3 microAmp. My speakers consume 20-50 mA during playback. Recording can't be done below 3 volt, but recorded clips can be played at lower voltage, upto 2.5 volt.
