I was looking around for a dictaphone for work purposes. In the organisations I have worked previously, they had much more expensive dictaphones costing over £200 to be used with a transcriber software. I needed something straightforward which doesn't require approval from IT department. After looking at many dictaphones, this model (for it's price) allows you to rewind / fast forward / overwrite / add. Many other brands which costs a lot more does not allow the mentioned features. The recordings are of good quality. It is easy to transfer the files into a computer as you would do with a USB stick. If you have a multimedia keyboard, you can play / pause the files that are played on windows media player as you transcribe the files.
The manual that comes with it is just a quick start guide and doesn't tell you how to add / overwrite files. [...] is the link to the operating guide which is more useful.
