Query: A Good Buy and Great Function

This product has several features that are helpful for me. The recording quality and volume is fine for my purposes, which is recording therapy sessions. It picks up all voices well. The interface with the computer is straightforward and simple, allowing easy data transfer. The small size makes it easy to carry and store in a purse or pocket. The product doubles as a flash drive, so If I don't have my flash drive handy, I can just substitute this. The product really eliminates the need for an additional flash drive. When the machine is off, the computer sees it as a flash drive. The format can be converted when writing to a CD, so that recordings can be played on a regular CD player. However, the size of the file has to be small enough to fit on the CD. I am convinced that for my needs, this was a good purchase and the best value I could find.
