Sonicare 2100 vs 4100 According to a WireCutter review dated September 2022, you can contact SonicCare and acquire a free plug adaptor. I recently purchased the 4100 from Amazon. I don't have the serial number yet because the product won't arrive until tomorrow, but SonicCare customer support just assured me that if I gave them the model number and serial number, they will give me the complimentary plug adaptor. They made certain that there would be no price. It will take 7-10 days for them to send me the plug adaptor when I provide them the serial number. I'll do all of that when the stuff arrives tomorrow. It certainly does. It makes a unique sound from the Toothbrush, but it is not an alarm with a tone. It is more likely that the vibrations change for a split second to indicate that thirty seconds have gone. I've had mine for four years and there is no mold on it, but I also rinse the gap between the head and the body every time I rinse the bristles.Sonicare 2100 vs 4100
