Summary: I bought this for my wife to record thoughts in the car and in the middle of the night. At about the same time she figured out how to make it work (two days) it stopped functioning. I fiddled with the battery contacts and got it to go it bit more. We then replaced batteries.
Summary: The Sony Balloon is a great buy. I use it to record brief memos (phone numbers, appointments, etc), and then pass them on to my Palm. Sure, the sound could be better, but it is good enough for you to understand what you've recorded quite well.
Summary: I usually remember something important or have some great idea while I'm in my car, but I don't want to try to write it down while I'm driving (too dangerous). This little voice balloon hangs from my rear view mirror and lets me record these ideas until I can get home and write them down.
Summary: I us this product to remind me of things I need to accomplish daily as well as things I will need to make notes of for future projects. In my line of work I have many ideas and thoughts being presented to me on a daily basis. I was trying to write all this down on paper.
