1: Recessed blade This automatic can opener features a sharp blade that is safely recessed within the unit. This safety feature helps prevent accidental cuts to your fingers when searching for the tool in your kitchen drawers. 2: Metal gear Using a can opener couldn’t be simpler with the straightforward design of the BangRui Automatic Can Opener. To open a can, position the rim of the can in between the blade and the metal gear. The metal gear guides the rim of the can through the can opener so it moves in a full 360° circle by itself. 3: Battery compartment The new Bangrui can opener is completely different from the original design in appearance. Moreover, it is designed with a plastic sheet in the battery cartridge, which further stabilizes the batteries installed. 4: On/off switch The simple one-touch button couldn’t be easier to operate. Simply press down to begin cutting the can, then press again at any time to stop the action. 5: Magnet When you lift the can opener off the can, the magnet on the BangRui Automatic Can Opener will also pick up the lid. There’s no need to fish into the can with your fingers! It is more hygienic and safe than traditional can openers because the strong magnet does all the work. 6: Insert 2AA batteries in the right poles The battery groove is marked with signs of positive and negative electrodes respectively. While installing the four dry batteries, users should do as indicated by the signs. Once installation is done, cover the battery and the product is ready for use.
