we use these exclusively to clean the waterbottles at our rescue. the brush is actually 2 brushes and each cleans different parts--the bottle and the nozzle.

Pros: this is a great help in cleaning water bottles

Cons: none

I use these brushes to clean my rabbit's water bottle. They are so useful for reaching way inside the bottle where my hand cannot reach. The smaller brush is great for cleaning the top portion of the bottle and other small areas. These are another must-have item for anyone that has to clean small-pet water bottles.

Pros: Makes cleaning water bottles a breeze!

Cons: none

Although I haven't used this particular brand, bottle brushes were always an imporant part of keeping my guinea pigs' and rat's cages clean and healthy. There is no other way to properly clean their water bottles, and if the water isn't clean, your pets will not be healthy. This is a must have for small-pet owners.

Pros: everything

Cons: nothing

I use these brushes to clean my guinea pig bottles. The smaller brush is excellent to get into the metal part where the water comes out. I've accidentally put a box on the brush and it flattened out. By the next morning it was back in it's original shape. Highly recommended.

Pros: 2 brushes in one

Cons: Still hard to get under the top edge of the bottle

these brushes work great to clean the hard to reach insides of water bottles. I definitely recommend getting a set of these to anyone who uses water bottles.

Pros: cleans better

Cons: none
