Professional reviewers praise the Osmo Action 4 for its larger sensor, 4K/120fps capability, 10-bit D-Log M color and robust 360° HorizonSteady stabilization, positioning it as a strong budget-friendly alternative to the GoPro Hero12. However, they note the stiff battery door and the lack of RAW video, 8K recording, and optical stabilization as drawbacks for high-end creators.
Everyday users love the camera's ruggedness, waterproof depth rating, and compact dual-screen design, often highlighting its ability to survive drops and perform well in low light. Recurring complaints focus on the difficult-to-open battery door and noticeable noise when shooting in very dark conditions.
Professional reviewers, such as a 2026 YouTube analysis, commend the KJ23Pro for its straightforward button layout, easy menu for clip length selection, solid night-vision performance and the added versatility of serving as both a body and dash camera. They also note the camera's rugged construction and minimal controls as strengths, while pointing out the need for a full manual, the lack of remote or app control, and a somewhat steep learning curve for menu navigation.
Everyday users appreciate the camera's reliability, long battery life, ample storage and flexible mounting options, especially for police, delivery and outdoor activities. Common praise centers on the wide field of view and effective IR night vision, while recurring complaints focus on the absence of a remote control, menu complexity and missing size/weight details.
