We bought the ‘Pro’ toothbrush three weeks ago, which was delivered with a complimentary whitening toothpaste. First impressions are excellent: the brush’s four modes and high power make it both more efficient and more flexible than the Phillips unit it replaced; while the toothpaste is having a noticeable effect. We’ve subsequently bought additional heads in a different colour to differentiate who’s who’s. If there’s any improvement I could suggest it would be to adapt the brush heads to include a colour differentiator but there’s no harm in having replacement brush heads in stock.
