Surefeed Automatic Feeder Microchip Intelligent Identification Anti-theft Cat Small Dog Pet Supplies If a microchip is embedded, you can register that chip. If not embedded, please use the included chip by attaching it to the collar. Currently, all microchips are unregistered. It comes with a very easy-to-understand Japanese instruction manual, so registration etc. can be done easily. I purchased this a little while ago and tried it for less than two months, but my pet didn't use it at all, so I put it away. Including the previous seller, the usage period is less than six months. Operation confirmed The batteries have been replaced with new ones. The entire unit has been wiped and disinfected with Pastry 77. The food bowl has also been sterilized with boiling water. There are fine scratches overall. Everything in the images is included. The fourth image is a silicone case for the microchip (unused). It is designed to be attached to the collar. Please read the profile. [New Concept of Feeding] With its unique chip recognition technology, owners can manage their pets' meals on a one-to-one basis without worrying about accidental eating. [Easy Management] Registered pets have a specific ID. When a pet approaches, only the correct ID can open the bowl lid. Unregistered pets will not open the lid to prevent other pets from stealing food. [Food Protection] The feeder bowl has a unique cover to prevent insects and dust from scattering and to ensure the freshness of the actual food.
