Concept of the Bowl is Great. Trying to regulate the flow I find very difficult. (Others I have spoken to with them also experiences the same problem.) Shut off needs improving, easy for me to say. Float also seems too big for bowl as it needs to be resting on bottom of bowl to shut off tap, otherwise the bowl overflow. AND then the tap will not open to maintain the water in blow. First float also filled with water. Do love the idea and I have purchased other types of floats to try. Our Rottie does seem to like the continual fresh water (Lawn when it overflows loves it too).
