The 8GB USB Flash Drive Micro Audio Voice Recorder by SpygearGadgets might possibly be the smallest and simplest audio recorder ever!
There is one switch to turn the voice recorder on or off. When you are ready to listen to the recordings, simply plug the device into your computer, and double click on the file! It's just that easy - no software to install, no batteries, and no cables or wires.
In addition to being a power voice recorder, this small device also works as a regular USB flash drive, so you can store all of your important documents on it as well - pictures, videos, word documents, or whatever you want to store on it.
The internal rechargeable battery will record continuously for up to 4 hours, and the massive 8GB internal memory can hold up to 160 hours of voice recording! To listen to your recordings, simply plug the device into your USB port on your PC or Macintoshcomputer, and double click on the file to listen.
This recorder has worked perfectly, I leave it in my dress shirt pocket and it records everything. I can listen to conversations in my office easily, and have even recorded conversations in restaurants and while walking outdoors - i just need to turn the volume up to maximum when playing it back, but it recorded the other person's voice just fine. It interfaces with all my various computers easily enough, just plug and play the wav file.
The recording USZB flash drive was repackaged with a slip of paper added for instructions. I tried recording and plugging into my Win-7 PC, but could never get it to register without an error saying "Please insert disk". Supplier is in China and the time and money needed to send it back isn't worth it, but maybe that's the idea?
