Bought these for my two boys. They worked great initially but after about four months one of them will not hold a charge and has topped working altogether. Really disappointing to invest this kind of money and have no guarantee of product longevity.

After about 1 year and half or so, the battery no longer charges. I am disappointed since my husband and have the similar electric toothbrush and it still works after 10 years. Is there a guaranty? Is there a battery replacement ? I find it ashame to have to purchase a new one. My 5 year old really likes her Frozen toothbrush and wish new oral- b were better quality as they were before.

My kids really like this toothbrush however I recently purchased a new one and within a couple of days it stopped working. Unfortunately I discarded the receipt and original packaging so am not able to return it to the store. Disappointed that this occurred and feel like I've wasted money.

I have an amazing son with special needs - brushing the old way was arduous and a twice daily fight. This brush has made this practice seamless and hassle free. Thanks!!!
