I am a smoker and drink too much coffee, so a difficult case for each toothbrush. My dentist has recommended this model about 10 weeks ago. My wife and I have since then also in action and are thrilled. It cleans very well, also protects the gums. With this brush, it is almost impossible to hurt the gums. Especially for this offer also a travel case was about what I think is great. The brush itself have remaining battery display and are also adjustable in several stages.
