I use this waterer but i noticed that they stand at the nipples for a long time drinking because they don't get a lot at one time. I usually set out a second option for them that allows them to drink more easily, but it couldn't be my overall watering system because it is too small. This waterer stays clean for most of the time, and you can put a lid on it to prevent it from getting stuff in it. it is also easy to clean. The best thing about this watering system? They can't kick shavings into it! I used to be out there cleaning out waterers every hour or two. Drove me nuts. Also, they take to it quickly and use it without much teaching.
