Why doesn't the new 4100 model have a regular plug ? why on gods green earth did they cheap out and put a usb plug in there ??

According to the review in WireCutter (Sept 2022), you can contact SonicCare and receive a free plug adapter. I've just ordered the 4100 on Amazon. I don't have the serial number yet, because the product doesn't arrive until tomorrow, but SonicCare customer service just told me that they would send the free plug adapter once I provide the model number and serial number to them. They confirmed there is no charnge. It will take 7-10 days to receive the plug adapter once I am able to provide them with the serial number. I'll do all of that after the product arrives tomorrow.

Does anybody make a single speed electric toothbrush? I'm so tired of cycling through the speeds

Cycling is the most effective way to brush each quadrant sufficiently.

What is the purpose of having two intensity modes? How do you know when you should use one or the other?

if you have more sensitive teeth and gums you can use the softer mode

What do the green and yellow lights mean? what about the beeping noise after the 2 minute brush? I thought low battery but is it replacement head?

Hi! When the brush head replacement reminder light of Philips Sonicare Toothbrush HX3681/24 lights up amber, kindly replace your brush head.

Great battery life, best toothbrush hands down

1000% my favorite toothbrush I’ve ever purchased. The battery life is outstanding I think I’ve charged it twice ever. It does a great job of cleaning and the thing stands up to some beating in my luggage while traveling. Plus it’s pink so that’s a plus!

Increíble! Limpieza grado profesional

Nunca había usado uno y escuchaba que eran muy buenos y que valían la pena. Por los dientes sensibles no opté por los que giran, me fui por este que vibra y pensé que quizá sería algo Meh! …Lejos de la realidad. Es un súper cepillo! Se siente MUY POTENTE en velocidad baja hasta puedes llegar a sentir tus dientes en peligro jaja pero no te causa daño, al contrario, con los manuales me estaba lastimando el esmalte y sobre todo había partes que se sentían difíciles de alcanzar. Este lo conseguí en oferta, solo viene un cabezal y es pequeño, alcanza lugares difíciles y se siente suave con las encías, definitivamente lo recomiendo para dientes sensibles. Hay muchas opciones de cabezales para diferentes propósitos. Solo 2 velocidades y muy sencillo de usar.Lo volvería a comprar sin dudarlo.
