This is great item I use 2 for watering 50 chickens.had the metal one for 3yrs but it rusted out.well the plastic ones no problem there.I just turn them up to wash out.Great item..for little money.

A fountain for our furry friend. Our dog loves this bowl. The last one we had worked for 20 years. I only gave this four * because it was shipped without the flow stopper. The folks at Miller Mfg promptly sent me two.
