    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.

    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.

    Great toothbrush. Only been using it couple weeks but teeth seem cleaner already. Really the only negative comment is that the Bluetooth connection from the app to the brush is very intermittent and does not connect most of the time. I'll likely have to setup again to resolve this.
