See if you can find a high speed camera to record the movements and study them.

I have a bunch of C3 brusheads and my diamond clean smart just died after 4years. I want a new brush but I don’t care about the bluetooth features. I actually didn’t even like the pressure sensor. I just want a strong vibration. Any suggestions?

I would look at the 4100 Series (USA) or 3100/4100 Series (Europe) they are very good for the price. Marginally better because slightly more powerful motors Sonicare ProtectiveClean 5100/6100 Series (USA) or ProtectiveClean 4300 (Europe).
