I recently purchased the transcription kit, even in the face of advice to not do so, and I'm very pleased that I did. I use a Sony ICD-P110 digital voice recorder, with version 3 of the Digital Voice Editor software from Sony. I only bought the transcription kit because it was almost half price, as I was unsure about how well it would work.
I have not been disappointed. The only problem is that if you save the MSWord document you're working on, the digital recording is reset to start playing from zero again. I think the save comand is activated in both programmes. I simply note my expired playback time before saving the Word document. I have also been able to play back mp3 files.
I am however very pleased with the overall package.
