Good to know- The set includes two handles and two brush heads so you don't have to argue with your loved one about who gets the first turn- The brush uses 3D cleaning, oscillating and rotating to effectively remove plaque and dirt- The round brush head is specially designed to best surround each tooth so you can get the best clean- If your gums need gentle handling, you'll appreciate the gentle brushing modes- Bring it on holiday - no need to lug the charger along when the battery can last for up to 10 days- With the 2-minute timer you won't need to guess whether you've brushed for long enough
