This is a great waterer. I was skeptical of whether it would stay put with just the grooves to hold it, but it does just fine, and is much easier to remove and clean than the supposedly no-drip one from petco I was using before. It holds a lot for my thirsty finches. Can't beat the price either.
These are great finch waterers! They are sturdy and stay on the cages well with the grooves in the botttom section that fits between the bars. Very easy to clean daily. My finches do not use the "ball-point" type of bottles, so these are perfect for keeping the water clean, too. The price is fantastic!
