Using a dedicated voice recorder has numerous advantages to smartphone apps; not relying on your mobile’s battery or storage space chiefly among them. The advantage that your mobile has is convenience: it’s usually close at hand. 

Enter the VRS22 Keychain Voice Recorder. It’s got all the features — like one-touch or voice-activated recording, 20 hours of continuous record time, and mp3/wav/wma audio playback — that you need for recording lectures, meetings, or personal conversations. The keychain design makes it easy to take with you anywhere, and voice activated recording helps keep you safe even if you’re not paying attention.
