Thank you for viewing. This is the Best Answer Co., Ltd. automatic pet feeder, model pet-072, in white. I used it for a few months when my puppy was young, but I'm selling it now because he no longer eats only dry food. It can feed your pet at any time and in any amount, and it can also record the owner's voice to announce mealtimes, making it a convenient feeder for when you're away for extended periods. The stainless steel food tray is removable and washable, so you can use it hygienically. If you're looking for one, how about it? Tank can be washed. Voice recording and playback function. Desiccant pocket included. AC power and battery (2-way power supply). Dimensions: Approximately 370x240x317mm (including food tray) Power supply: AC adapter (5V-1.0A) or 3 single alkaline batteries (sold separately) Materials: ABC resin, stainless steel Weight: Approximately 2.3kg Tank capacity: Approximately 4.5L Set contents: Automatic feeder body, food tank, food tray, stainless steel food tray, power cord with protective cover, desiccant *Compatible food: 5-15mm dry/freeze-dried dog food or cat food (depending on the shape, it may not be compatible even within the size range.) *I have lost the instruction manual, but there is a setup video on YouTube, so I think you will be able to set it up without any problems. Thank you.
