Purchased in December 2024 at Yodobashi Camera. It's rechargeable and cordless, so you can use it anywhere. The charge lasts about a month. It holds a lot of water. I bought it for my cat, but it was actually for a dog. There's no original instruction manual, but you can find details online. The customer service is helpful, and you can ask questions right away. I used it for my cat for a while, but instead of drinking the water, she played with it, and there are teeth marks on the dish, but it doesn't affect its use. I've cleaned it thoroughly and wiped it with paper towels. It comes with an unopened dedicated filter, a hose filter, and a charging cord, so it's ready to use immediately.
