I have been using this product for my two fussy felines and it continues to be a big hit! They love to drink from the spout rather than the bowl, and, of course, it's a great place to play. Loved mine so much I bought the large version for a friend's dog. It was just as big a hit with him.
Anytime I remove the reservoir the plastic lit falls off. Also the o-ring for the reservoir cap fell out and is non replaceable by the manufacture. I called and they were kind enough to send me a new reservoir at no cost since I have only owned the unit for a week. Could I be the only one to need a replacement o-ring? I still have the original Drinkwell which is about 15 years old. It's a little noisy but still keeps working. I have to kick it once in a while to get it started though.
