Brothers® 16GB Flash Drive USB Digital Spy Voice Portable Dictaphone Recorder
Spy Voice Recorder good purchase
Does a better job of recording than I was expecting for such a simple device. As a thumb drive it only has 16 GB capacity so it’s not a thriller in that regard but it does an excellent job of recording ambient noise. You can place it on a key chain and then innocently leave the key chain on a table top to record a conversation.
