Query: OK

This is OK for some voice recording. It can also store data files.The first big problem I had with this was it would switch off onits own, even with new duracells. It would stay on for around 15minssometimes then turn off.The noise and clicking if it is touched or held is a little tiring butwhen it's on it is quite useable.Next purchase will be a more reliable pro model.
