1. Super powerful. 2 to 3 million pixels is 2-3 times the resolution of 1 million pixels. This is a truly super powerful bright otoscope. It is suitable for all smart phones, has the function of taking pictures and videos at the same time, and has two separate dedicated applications for the left ear and the right ear. 2. Magical orientation. The three-axis intelligent directional gyroscope can prevent the image from shaking or inverting, and has a magical directional effect. Without its otoscope, the image will swing upside down, forming a mirror image, making it impossible to distinguish left and right, up and down, front and back. How important is the truth when solving problems. 3. Seiko production. The entire product needs to go through 31 mechanical processes, 4 manual processes, and 42 assembly processes to be manufactured. The small switch is bright at night and turns off automatically at regular intervals.
