I bought this for recording meetings. It's great for long recordings. I've been using it for about two years, and while there are a few scratches, it works perfectly fine. 【Fast Startup】: One-touch recording. Slide the record button up to start recording directly. Compared to regular IC recorders, this has a one-touch recording function even when the power is off. Compared to the previous model, it now starts recording within 1 second of turning on. It's easy to use, so even those using a voice recorder for the first time can operate it smoothly. 【Long Continuous Recording】: This voice recorder is equipped with an 880mAh lithium battery and can record continuously for up to 144 hours. With a full charge, the maximum standby time is 150 days. Also, you can record while charging with an AC adapter, so you don't have to worry about not being able to record because the voice recorder's battery is low. Moreover, it's only about 70% the size of a regular voice recorder with an 880mAh battery, about 1/4 the size of an iPhone 13. The compact design makes it convenient to carry. 【The Strongest Noise Reduction】: An IC recorder loved by professional audio professionals.
