I love how much more disassemble-able it is compared to the older one. I can keep it much cleaner, much easier. My kitties are drinking much more water, which was a worry I had, and my 20 pound boy has stopped asking for the bathroom tap to be turned on. We'll see how long it stays clean, and how long the battery lasts. I clean it and charge the battery once a week. The older plastic one I've had for the last couple of years (given by my parents when theirs kept taking it apart) was starting to get harder to clean, and the battery was starting to need charging more often.
