This is my second Diamondclean toothbrush and I love the product however both toothbrushes have stopped performing well and the vibration is muted just after the warranty period elapsed - 23 months. This is disappointing for the top of the range product. I still have an earlier Philips toothbrush that was an entry level product and it is still working fine. There is a flaw in the design of the diamondclean model. Such a pity.

I love sonicare but it is my second one that has malfunctioned in less than a year

I've used Sonicare toothbrushes for more than 15 years and Diamond Clean is the best of the bunch. It cleans more easily, has a greater range of useful settings and I like having a chargeable case. I would prefer it came with the option of a stand-up charger adapter to replace the pseudo-glass, but the "glass charger" works fine.
