Bought brush for about 400 dollars which included spare brushes, which as you could imagine, soon needed replacement.
Ordered a set of 3 for over 40 dollars, which took over a month to arrive!
The first Sonicare DiamondClean brush we had lasted about 2-3 years before it no longer worked, and Philips neither had parts or repairs for it.
The brush itself does a good job, but it is a pity that Philips uses such unreliable technology and is so greedy charging so much for just three plastic brush head replacement.
My opinion is that the Philips Sonicare DiamondClean is not worth the money
