Query: Excellent poduct

its very sturdy aluminum casing. It records excellent audio from the speakers of an auditorioum even when there is a large audience present. its very easy to use. its small enough that you can put it in your shirt pocket. AndI have a Mac and it sinchronizes perfectly with it.On the normal mode of recording can record up to 13 hours and the batteries last a good 13 to 15 hours.I would recommend this product. even though its a bit pricey. If it wasn't because of the price...i would give it 5 stars.
