have brought the TriZone as successor to my Oral B Triumph 5000 me a few months ago. Basically, there is no difference, except, as already mentioned several here, the brush attachment. The TriZone brushes are also going smoothly on the Triumph 5000 ... inzw. I used again even the normal brushes, as these in my opinion better than the brush TriZone.
Why I switched back then? My Triumph 5000 died of something that obviously any Oral B Brush dies: the battery. Mir is not understandable how still relies on this slow and not long-lasting technology and not umsteigt batteries to lithium ion. The load times of NiCad batteries are underground and they break quickly. After 3 months, is now also my TriZone "broken" because no longer the battery is charging. A simple exchange is not possible and also not provided. Outrageous.
So I have now unfortunately go to the competition! : /
