Overall, I’d say this product was okay. But it was very complicated to use (or at the very least, not quite as easy as advertised). Sometimes the functions would work when you pressed them, other times they wouldn’t, so it was hit or miss. Also, it seemed to skip a lot, even though music (or conversations) were continuously going, it would still skip (like when a CD skips for a few seconds). And be aware that if the internal battery is fullly charged, and you attach the external battery right away (for example, you’re in a recording session that you know is going to take longer than the internal battery life time), it will still STOP recording once the internal battery dies, it will NOT automatically switch over to the external battery. So you will have to go back and re-activate the recorder. So overall, it was okay. It did most of the job, with some difficulty. But the customer service was great and always available to help without any wait times, so that was great.
