Thank you for viewing. Regarding your purchase, I have written requests and precautions for transactions in my profile. Please take a moment to read it to avoid any problems. Wannyangurume CD-600 This is an automatic pet feeder. I purchased it several years ago and only used it when I was away. I haven't used it very often. I have washed the food container, disinfected it with alcohol, and sun-dried it. However, please note that there are some parts that I couldn't clean. I only used one tray. The one I used has scratches from use. You can't operate it with a smartphone, but I liked it because it allows for more precise gram settings than other feeders, and you can set up to 5 different feeding times. However, I'm selling it due to moving. Operation has been confirmed!! There is no original box, so it will be bubble-wrapped for shipping.
