The Korean package includes a Korean manual, making it easy to operate. I think it would have been a bit confusing if there wasn't a manual instead of an app. There is a Korean typo in the manual, and there are parts where the meaning is completely reversed due to the typo, so Korean readers should take note. When all the water droplet shapes are lit up, it means it's full of water, but when they are all lit up, it says that the flow rate is 0, so water doesn't flow out and it doesn't dispense. I think I made a typo by switching from "off" to "on" when I meant to say "on" when it's turned on.) There are up to 6 settings, but if you use all 6, the water is consumed very quickly, so I'm not sure if it's right to set all 6. For now, I've set up all 6 patterns to take a look at them. There is not completely no noise. Still, I think it's better than a water purifier that keeps circulating water through a pump. It only makes a sound when the water is being dispensed. I'm so satisfied, and when the cats hear the sound of water, they come running to take a look. It's not crude, but luxurious. The parts are all high-end too. There is no spillage at all when pouring water. Our second child at home plays a lot with water, so most of the cat water bottles get knocked over or spilled every two days. I can't knock this one down at all. That part is really, really good. It's really convenient to have no wires. I regret the time I spent worrying. On the official Korean website, it's almost twice the price, but if you look for it, you can find it for around 5-60,000 won in Korea as well. It might be better to give a coupon and have them buy from here.
There is a Korean user manual, and the product is not cheap but high-end.
The cat is still just exploring out of curiosity! ^^
