Ridiculously easy to clean and all parts feel extremely high quality. It's nice and quiet so it doesn't spook our new cats, and the sensor and timer modes are easy to toggle between. We usually set it to timer during the day to preserve battery, and sensor at night so it doesn't come on and light up when the cats are sleeping. A full charge lasts us about a week and it recharges easily and quickly. The instructions are super clear and the deal for extra filters on top of the ceramic pieces makes this a much better deal than any other wireless car fountain on the market that I've found. We also got a very sweet note hoping our cats liked the fountain with our order slip. Could not recommend more!
