While the small size of this camera makes it great to take around, and easy to use, it apparently doesn't come without a price. When I brought my Elura 2MC home, and shot a few minutes of test video, I was shocked to discover just how loud the motor noise was on the recorded video. Although there is a built-in noise filter, it seems to have no effect on the constant hum from the motor while filming.
Given the price, I assumed that my camera had a manufacturing defect, so I took returned it for a new one. Unfortunately, the second camera had the same problem. While the camera is otherwise quite nice, the constant, annoying background really ruins the video it takes. ;-(
