Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Curaprox Hydrosonic Pro. It's more expensive but it works great as well and it say it's made in Switzerland. By the way their manual toothbrush are amazing. Worse the price as a long term investment.
Smaller brand of great quality better than made in China ones? : Curaprox.
Curaprox. It's a sonic type that I find relatively quiet compared to others.
Have you checked out the Curaprox Hydrosonic Pro? I am obsessed! and it does not get gunky like my old Oral-B
Also folgendes, man gewöhnt sich dran. Wirklich. Wollte ich am Anfang auch nicht glauben. Ich benutze Handzahnbürste und Schallzahnbürste abwechselnd und immer wenn ich ne Weile nur von Hand putze und dann wieder zur anderen greife, ist es wieder unangenehm im Mund und auch in der Hand. Aber dann beim 2. oder 3. mal nicht mehr. Die meisten Schallzahnbürsten können niedriger eingestellt werden. Was langfristig nicht ganz sinnvoll ist, weil das die Reinigungsleistung beeinflusst, aber es ist perfekt für die Umgewöhnung. Ich habe die schwarze Curaprox, glaube die hat 3 oder 4 Stufen. Die weiße curaprox pro kann man, wenn ichs richtig in Erinnerung habe, niedriger einstellen (kostet dafür mehr), ansonsten sind die gleich.
I can also recommend this one. I had a problem with mine (button fell out), I contacted them, and despite it being out of warranty they replaced the whole toothbrush it with a new one (after I sent the old one to them). Excellent customer service! However, I think any of them is good, and you should get what suits your budget.
I honestly believe that Curaprox HYDROSONIC are the best \[I have tried both Oral B IO series toothbrushes and Philips Sonicare and the Curaprox gives a superior clean and has very gentle bristles made from another fiber, I also like the fact it is Swiss made\].
I also had mine replaced, but then found out that the button may suffer from water and toothpaste residuals, so trying to dry that well after use seems to help make it last
