    MOLD, MOLD, MOLD, MOLD, MOLD! Only 1-2 months and all the insides of the head and stem it attaches on to got MOLDY. This NEVER happened with my SonicCare. I thought I could give Oral B a second chance after months of using their early brushes in my teen years. Never trusting Oral B again.

    If I could give zero stars, I would. The battery doesn’t even last one full day (after about 3 weeks). Not sure if I got a defective one, but it is no longer returnable. The toothbrush is also very messy. I’m a person who likes to do things when they brush their teeth but with this I have to stay at the sink at the whole time.

    No, I would not recommend this to a friend

  • Should have stuck with Sonicare

    I like that it cleans effectively. I realllllyyyy dislike that the toothbrush head collects water and mildew or some gunk collects in it. Makes no sense to buy a toothbrush that needs a q-tip and toothpick to clean. Too later to return.

    This sonic vibration is really weird. Have no feeling it is actually brushing. just vibrates my teeth, very uncomfortable.
