We purchased this unit based upon Eastman Kodak's reputation for ease of use and photo quality. This was to be a replacement unit for my Z730. The latter being too big and bulky for my current needs. Based on previous experience with Kodak, I decided to give the M381 a try. Being familiar with the Kodak interface from my previous camera, I felt confident that I could pick up the new camera and get excellent photos immediately without needing to suffer a learning curve.
Features I liked: Small size, big LCD screen, familiar menu / user-interface, battery in-camera recharging.
What I didn't like: Photo / Video quality.
We took our new M381 out for a test drive at Disneyland today; unfortunately nearly all of the photos we took were overexposed, grainy, or completely washed out. Even the best photos had broad pixelated stripes through the photos. The videos were grainy and overexposed as well; fortunately not as badly. Our trip today was for my wife's birthday; unfortunately none of the photos we took on this trip are useable. While I do like the simplicity of the operation of Kodak products, I cannot endorse this particular unit. While your experience may (hopefully) be better than ours, my confidence in Kodak's quality control has been devastated.
I can't comment on battery life as we were not going to keep it long enough to find out. We aren't planning on taking enough photos or videos to kill the battery; we'll be returning it as soon as possible. While it might be worthwhile to return it to get a new unit of the same model, I'm no longer confident the quality control measures are in place at the manufacturer. I can ill-afford to miss more memorable moments to defective cameras.
I might someday return to Kodak products, but not for some time.
