Amazon.com: Customer reviews: 5 Modes Electric Toothbrush with Travel Case, Rechargeable Sonic Toothbrush with Smart Timer and 4 Brush Heads, Waterproof USB Toothbrushes Up to 30 Days Battery Life Black
This toothbrush is not strong enough. I’ve used SoniCare for years and went with this cheaper model when mine died. Not a good experience. My teeth weren’t half as clean as they are with my SoniCare. Spend the extra money and get a better brush.
