    The application along with the toothbrush makes a perfect combination for your teeth. The toothbrush comes in a very nice travel pouch and the charging cup always keeps your toothbrush charged. If im being nip picky i wish the ppuch came with a usb to charge the toothbrush on the go, but for my type of getaways which is 3 to 4 days this toothbrush easily makes it to through the weekend. I would highly recommend this product if the price seems reasonable to you. Investing in your health personally to me is not a waste of money.

    Yes it’s expensive but I’ve only used sonicare for around twelve years now. Fantastic products and this is definitely worth the investment if you can afford it. Everything about this toothbrush makes me happy, the app took some getting used to. I have quite a bit of money in my mouth already and it’s imperative I keep my oral hygiene in top shape. This feels like you’ve just left the dentist with super smooth teeth and unsurpassed fresh breath. My last brush lasted ten years and was still functioning upon upgrading and I have no doubt this one will be the same. Thanks sonicare!

    The best toothbrush in the market! I get it, it's pricey, yes, but I promise you it's worth it. Had it over a year, came with two replacements, had to buy a couple already since it has to get replaced every so often. Works very well.

    So far so good. Getting used to the app and learning to maximize the use of the product. So far no complaints. My husbands hates the glass cup/charger combo. I think it could be different/better considering the amount it costs.

    Easy to use with fantastic results. The base is a cup and a charger. The app will show you where you might need more brushing. Well worth the price

    I've been using Sonicare for a long time. Great investment to keep your teeth clean. First time I've purchased black. White is better. But, it's a showpiece in the bathroom. Expensive but worth it. If money no issue, buy it. Just keep it clean. Happy brushing.
