This is an automatic pet feeder robot. I cleaned and sanitized the inside before listing it, but the scent of pet food remains. Minimum feeding amount: 5g Maximum feeding amount: 100g You can set up to 4 meals a day with the timer. You can also set the amount to feed each time. You can also record your voice, which can be played when feeding. You can record your voice, such as "\[Pet's Name], it's dinner time!", to let your pet know it's mealtime. A USB cable to AC adapter is also included, so you can use a power outlet. Ideal for feeding dogs, cats, and other small pets a set amount of food at set times, and perfect for when you're away or traveling. Instruction manual is also included. Some of the new film has not been peeled off. A paper instruction manual is included, but the cover is dirty.
