Small flash drive size slightly bigger and thicker than SD card pocket size recorder with built in battery that can be recharged using USB or USB C charger with adapter provided for charging cable. Recorder has magnet built in for easy mounting on file cabinet, refrigerator, or carry it on lanyard supplied. USB C headphones provided has all necessary functions to check replay of recording. Nice feature is that connecting recorder with USB cable to PC or laptop allows the recording clips/files to be downloaded and can be played with Windows media player. This allows using programs/apps to transcribe audio to text. I have yet to check this function out completely. Photos of files on recorder is shown, and the clock time/recording time is set or changed from default. Also changed is the text default file of recorder for recording to be loud enough for me and quality. This needs to be further explored. I plan to use this for customer meetings and discussions. Either it can be an audio report or transcribed text document. It will be handy while listening a webinar or training class so I do not have to write notes. Overall pleased with the quality and portability size of recorder.
