Thank you for viewing. This model has image stabilization and 4K video capabilities. I mainly used it as a motorcycle drive recorder. I've dropped it on the ground, case and all, twice, but there are no malfunctions, major damage, or dirt. Dedicated protective films to prevent scratches were applied to the front camera area (two places) and the rear LCD screen when purchased, so there are no scratches on those three areas of the main unit. (Please replace the films if necessary.) There are only a few minor scratches near the top recording button ⏺️. Operation has been confirmed. It has never been used underwater. There is no battery swelling, and charging works without any problems. (Charger and two battery packs included) SanDisk MicroSDHC 32GB (new) included. All accessories are shown in the photos. Thank you very much.
