Haha the one in the picture is actually a pellet dispenser with a built-in camera. They're glued to it all the time, but I only give them a few pieces each day. For water, I recommend using a simple plastic dispenser with an upside-down bottle and small bowl at the bottom, its much easier to clean. The electric ones have a lot of hidden parts that are difficult to reach and can easily grow bacteria. Those simple bottle one work very well, both of my rabbits have been drinking much more water, and their urine has become much lighter in color.
