I first bought this product when I was studying - I already had an older dictaphone that used a tape, but thought that since I was planning to use it a lot, I should invest in a more recent model. In hindsight, this was a mistake.
There are lots of good things about this Sony model - although it costs over a hundred pounds, it captures sound really well, and gives you really clear, audible recordings that you can upload to your computer and use and you see fit. Its buttons are pretty easy to get the hang of, and the screen means you can keep track of time elapsed, fast forward and rewind more accurately, choose the recording you want - all the benefits of digital technology, really. I really like these features, but in truth I didn´t use many of them.
Most of all, I found that I missed using the older, more traditional dictaphone, which was just more satisfying to use, and felt more intuitive - I loved the rewinding sound, and found it easier to use in the hand. Every was well-designed, and while there are less options on an older model, I don´t enjoy using this as much - I feel like I´ve got less control over the recordings. Also, battery life isn´t as good with this model.
Overall, I think this is a good dictaphone, but perhaps it´s best for professionals. If you´re a more casual user, then the older, cheaper ones might be better - for me it wasn´t a good investment, but I can see that it´s a good machine.
