As ceramic is a material that easily slips, if you get such a model, be sure to improvise something so that is does not. That way, you can ensure the bowl does not risk breaking easily. Accidents happen all the time, so try your best to avoid some of them if possible. Once this issue is solved, the only thing that is remained to be said is how often you need to change the bowls. If they do not break, that does not mean that you should not consider changing them.
