Summary: A little larger than I anticipated but that is the only demerit. Works very well. I use the cardioid (directional) mikes built in and have made dozens of live recordings. Plenty of settings give the user full control.
Summary: I bought this to use professionally with a Canon 60D. This recorder is amazing. It has a headphone out and another output for the camera. I've used it on many professional projects with dozens of satisfied clients over the past 3 years. The best feature to this product is it's dual batteries.
Summary: Excellent digital recorder. Recordings are very clear and dynamic and don't distort if you choose the right setting. There are many options on this recorder such as playback at different speeds which doesn't change the pitch, and overdubbing.
Summary: I used this to record audio for an independent film, using the XLR inputs. The quality is good, but I ran into severe problems with the battery. After the Li-Ion rand out (about 4 hours of intermittent use) I had to change out AA batteries every hour.
