I bought this device to aid practice as it's very difficult to judge the overall sound of a duet when you're actually playing one of the parts. I was not disappointed.
This is an excellent recorder providing a superb stereo image. Extremely good recording quality and it works straight out of the box, just load two batteries and away you go.
Very importantly, and unlike MP3 recorders I've tried, the H2 accurately captures the attack of "difficult" instruments like concertinas beautifully and it works equally well with percussion.
The box includes a memory card, headphones, USB lead, stereo jack to phono lead, desk stand, windshield, and a little pouch to keep the recorder in. Basically it has everything you need to start making useful recordings.
If you're looking for a good general purpose semi-professional recorder I'd recommend this one.
