Query: Not Worth the Duck (Buck)

This water bottle is absolute rubbish. I bought two of them thinking they would be nice for my hedgehogs. They hold a lot of water and don't obstruct the view into the cage. The duck water level is cute too. Aesthetics are the only redeeming qualities for these water bottles. Functionality is zero. A single band is supposed to keep up the bottle but when full of water the weight is too great, it drops out onto the cage floor. I had to jimmy my own fix to this - why buy a product that doesn't work. Additionally, once full, the bottles literally spewed water. I tried multiple times and came back to a flooded cage. I would never buy these again and have instead started using a dish. Don't waste your money on these or risk that you leave your pets with no water.
