I used it outdoors only once after purchase, and haven't used it much since. The exterior is very clean, with no noticeable scratches or stains. All functions work perfectly without any issues. Compatible with both a single camera and an action pod. Dual magnets and a buckle locking system ensure safety. Quick-release specification for easy attachment and detachment with one touch. Easy adjustment with an angled 2-prong adapter. Thank you for looking.
