Mediocre camcorder, but for such a price you can't expect perfection. Changing the battery resets the date/time to the date/time of the last entry, so resetting is a bit cumbersome if the date/time information is important. Another limitation is the inability to shoot with the side LCD screen closed, as closing it turns the camera off (not sure if this is typical of all these small cameras, but it thwarts some of my expected uses). The night vision function works very well. Internal mic only as others have mentioned. Overall it seems like a good option at a reasonable price. I bought an extended warranty just in case
