ZDNET reader reviews the Bebird Earsight Plus D39R, a portable earwax removal camera that costs under $20. The device is a waterproof, dustproof, and fogproof camera that can be used as an inspection tool. It also comes with camera adapters for nose, teeth, or throat. The flexible head has length markers so you can see how deeply it's been inserted. The camera is rechargeable via a USB-C port on the end and IP67-rated for handling dust, rain, splashes, and accidental submersion. The Bebird app allows users to control the intensity of the camera, adjust magnification, and capture stills or video. While the camera is more expensive than basic alternatives, its superior design, flexible build, and advanced features make it a far better overall product.
