Just received this electric toothbrush, purchased because of princess Belle theme. I had expected the brush head to be replaceable because Amazon presented this item as frequently purchased with the "Braun Oral-B Stages Power Kids Replacement Brush Heads Disney Princess 2 Pack" (ASIN B003NHJ9A4). To my amazement, the brush head is permanently fixed and definitely not replaceable. So, this is essentially an electric toothbrush that becomes useless once the original head wears down. What an expensive throw-away toothbrush for £13!!
