Summary: I used this a few times. Records in compressed Mp3 / and uncompressed formats at various sampling rates. Onboard mic's decent. I was not able to get more than about an hour of battery time while recording.......have not tried battery usage in the various compression formats, but the Zoom recorders seem better with battery life in my opinion.
Summary: I purchased the Teac VR-10 in white from Amazon, LLC. It's a compact portable digital record but with outstanding audio performance. It has no internal storage, but ships with a 2GB microSD card. I have used an 8GB micro SDHC card successfully with this recorder. I used this recorder for the audio portion of our product training series on YouTube (youtube.com/scalearctraining).
Summary: You can download the TASCAM DR-08 manual because it is the same (except for 24 bit/96k recording) . You can also easily update the firmware with TASCAM DR-08 firmware and add the above functionality. Search for the VR-20 firmware hack and substitute the VR-10 firmware. When I turn mine on, it says DR-08. The only thing I noticed was that the line input signal level wouldn't drop to zero when turned down to zero - it does that out of the box.
Summary: I use this whenever I get an idea for a rhythm in my head. I just pull it out, turn it on record, and then start humming or whatever. Later, when I have more time, I can sit down and play the guitar or drum machine or piano to get the idea onto the computer. Works great for what I bought it for. It is simple to use too.
