PetSafe Healthy Pet Water Station, Dog and Cat Water System with Stainless Steel Bowl, Large, 320 oz.

So far I'm really liking this with the 2-gallon reservoir. That much water stays cooler longer, and the opening for the water is large enough to be able to pour ice in if needed. I like that the container isn't white like the picture, but is translucent so you can see the level of the water; however, I don't know if that will be good in the long run as that can allow the sun to warm up the water and allow things to grow. There isn't a lot of pressure to push the fresh water down into the bowl, so if there is any slime or dirt in the bowl, it just stays there, but having a stainless bowl in the bottom is much better than the plastic! Got the big size for my big dogs, but need to elevate this - wish it had some sort of an add-on stand or taller bottom for it, as it is pretty much as shown - bowl right down near the ground only a few inches.
