This recorder boasts an impressive 28-hour continuous recording capability on its built-in battery. If you use it with the sound on for 7 hours daily, the battery can power it for up to 4 days of recording. In scenarios where you record for 4 hours a day, you can expect the battery to last for an impressive 7 days.

Recharging the battery is a quick process, taking just 2 hours. If you're in a rush and can't wait, consider having two recorders on hand. This way, you can easily swap them "in the field," while the other one can be taken home for peaceful listening.

For longer recording needs where access to a charger may be limited, we recommend the 7/14/30-day version—a larger recorder concealed within a rechargeable battery. However, if you anticipate more frequent access to the recorder, the USB stick version is the ideal choice, given its compact size.

The recorder also features a sound-activated recording option. With a single charge, it can remain in standby mode for up to 25 days, but in practice, it can record sound for several days with moderate "trigger detection." This combination of features ensures a reliable recording device with crystal-clear sound capture from up to 10 meters away.

**Customer Testimonial - TJAŠA (Rated 4.5/5 based on 1717 customer reviews):**
"I love how easy it is to use. I've caught someone cheating multiple times, and you can place it virtually anywhere with tape, Velcro, or a magnet. I recommend this product. But be prepared to listen to the whole recording from start to finish. I only left it for one week to gather information. Stay calm, don't get excited, or go crazy. Just get the information and leave the cheater behind. A cheater will always cheat. They try to justify themselves, but in reality, they are NOT good people. I hope to help everyone who is dealing with cheating. Trust your intuition; it's always right! Tjaša"
