Philips Sonicare Series 7500 HX7420/12 White

In my experience, the Sonicare breaks too quickly, the head is then broken and no longer vibrates. As you use it longer, the "vibration" becomes less powerful each month.

The 2nd one broke after 6 months The 1st (type Philips Sonicare FlexCare HX9172/10) also broke between the 1st and 2nd year.

Bought this toothbrush in July. It is now December and I have just sent it in for repair at Cool Blue, where I bought it. It is (already) broken :( I thought that was a huge disappointment, because I expected more reliability from a product in that price range. So in terms of brushing I am very satisfied with this toothbrush, but certainly not in terms of reliability.. I use it twice a day with my wife in accordance with the instructions for use and personally think that the thing should not break within 4 months.

Have been brushing with Sonnicare for years, previously also tried Braun, but find that Philips gives a much cleaner feeling and a nicer brushing experience (it vibrates more while Braun rotates back and forth)
