Too rigid
I am always looking for the most efficient way to brush my teeth. A three-headed toothbrush seems pretty efficient! I wanted to love these toothbrushes,  but I found that they were hard to maneuver when you're in the process of brushing because there is no flexibility to them. The head of the brush is hard plastic so when you move around your teeth, the plastic hits your other teeth. It's not very comfortable or efficient.
