The Camera Arrived well packaged and undamaged. It delivers three Frame sizes and their framerates. 1920x1080@60FPS, 1280x720@120FPS and 640x360@260FPS. Good enough for me. Note that you need to use a software package that let's you pick all three framesizes. The default camera app in windows 10 only let you pick 1920x1080@60FPS. What I learn about the lens: the 5-50mm has three adjustment options: Zoom, focus and light. They are somewhat hard to adjust , shifting them carfully for the best result.
The product was listed as USB 3.0 device when ordered (seller changed description to remove 3.0). The product is advertised as 120 fps at 1080p, 60 fps at 720p. The max I am able to get is 5 fps at 720p using a USB 2.0 (which is the only supported protocol) under linux. Total rip off, buyers beware.
