"Over the last 6 years I've had 3 of these for cats and one of the bigger ones for a dog. I've never had a bit of trouble with them - none have broken, none have leaked, none have cracked or scratched. The one I've got now is over a year old and looks like I just bought it. I've always had the blue ones.
I do find that if left for too long between cleanings, a bit of water-bowl slime will grow in the angle around the bottom of the bowl and around the little spout that lets the water through from beneath the reservoir keg, requiring some fingernail work when cleaning. However, with two cats who love to drink water, the bowl gets cleaned a minimum of once a week and the slimy-ness is kept to a minimum.
I'm not sure about the feeder; I've never used one before but may be getting one in the future. However, I'd DEFINITELY recommend the Le Bistro waterer for anybody with cats. Not having to bend over to pick up an empty water dish for filling every day is really, really nice."
