EDITED TO ADD: the seller reached out after I left this review and told me the heads are replaceable! Mine didn't come with extra heads and I didn't realize they came off. Thank for reaching out! It looks like the product even comes with replacement heads now and you can also buy them separately. Perfect! These are great. _________ My kids love these toothbrushes and I love that they're rechargeable without needing batteries. However, the charging feature is almost completely negated by the fact that you can't replace the heads! It would be a 5 star if you could swap those out.
