## Questions & Answers

**Q: 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 ??**
A: 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.

**Q: Does anybody make a single speed electric toothbrush? I'm so tired of cycling through the speeds**
A: Cycling is the most effective way to brush each quadrant sufficiently.

**Q: What is the purpose of having two intensity modes? How do you know when you should use one or the other?**
A: if you have more sensitive teeth and gums you can use the softer mode

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