Comments: These water bottles are nice looking and so far they don't really leak or jam/clog. The main thing I do not like about them is that the white ball that helps you see the water level falls out very easily so it would be easy to lose. Other than that I am quite satisfied - I like the color and the 4oz size (my mice drink barely an oz a day, so I just end up dumping water out everyday and this way wastes less water).

Comments: Best water bottle ever! Wanted the purple but got the green. Oh well.. Doesn't leak and has a cool pearl inside to show you how much water is left. 4 oz is perfect for my hamsters. I just wish I was able to pick the color!
