For those of you who have used MWF over a long period of time, is it normal for the puck to develop cracks?

On a side note, I just broke my bloody MWF bowl few hrs ago...I was bowl lathering and it hit the faucet and wham, it broke into pieces and the puck fell into the sink. Luckily I didn't cut myself. Didn't like that bowl anyways to be honest. Time to look for a mug with a better grip.
