This article is just perfect, and saved me more than once. Having attacked amphi studies, it is not easy to take the course, and through this voice recorder I have no worries for all of my classes! Easy to use, just turn it on and click the save button and then stop when it has finished. You can play them over directly on the device (in speakerphone mode, or with headphones) or simply transfer them to a computer using the supplied cable (the recordings are in MP3 mode). I also find that the batteries last long enough, knowing that I record my classes 4 hours non-stop, every day and I often re-listening part the day pounding the last 2weeks to 3semaines. Possibility also to a micro SD card to expand the memory, something I have not done since he already recorded for something like 75-80h. From memory, it does not seem that there is backlight for the screen but personally it's not a problem. I never listen to my recordings without light for working nearby. Finally, the recording quality is good, I have only tested that auditorium, and I intend prof, but obviously we should avoid talking next door if not necessarily more we hear that what we hear the teacher (even if understood still in the background). Well, I hope I could help you a bit, knowing that I myself have been a lot of trouble deciding!
