Used for about 2 years. This is the "Kari-Kari Machine V2" automatic pet feeder from Uchi no Ko Electric. It was a great help at our house, but I'm selling it because I'm upgrading to an automatic feeder with a camera! It has been used to some extent, but it has been thoroughly washed and is still in usable condition! Only the main unit and power cable are included. I don't have the 5g propeller, so it can only be used in 10g increments.
