Great Technology

July 29, 2013

Very easy to use. I use it to record radio broadcasts in stereo. Just plug the earphone output into the line input on the recorder and the broadcasts are automatically converted to mp3 files. The program that comes with it makes it very easy to edit your recording into tracks. Buy it - you won't be disappointed

Very versatile and handy

August 25, 2013

This audio device has been perfect for me for several reasons
1) It records in MP3 format and can play music and other recordings that are in MP3 format.
2) It connects directly to a USB on a computer and appears as an external storage device for easy transfer of files
3) It also stores files that are not audio
4) The sound is amazing. I was able to record a flock of birds (the sound of their wings) as they took off from the trees in my yard.
5) I am able to connect it to my car AUX input to listen on my car speakers.
6) It is easy to switch between the 5 folders ... making categorization simple.
7) It holds over 30 hours of high quality sound; plenty of room before I back it up to my PC and begin the next 30 hours.
8) The rechargeable battery works great ... recharging while it is connected to my USB on the PC. I have not run out of charge yet, and I have used this daily for 9 months.
9) As you switch between folders, it remembers where "play" left off when returning to a previous folder.
There are many more features that I have not used. For the price, this has been the best audio device that I have owned (I have had 4 previous devices).
I have recommended this product to friends and have even bought this device for a friend ... a friend who loves this product, also.
