The rechargeable battery is always 1x Loaded a week to 2x. Approximately every 4 months I let the "machine" as long run until the battery is empty and then charge in one again.
The Professional Care 1000 is Sufficient for me, because I found the other functions of the 2000 or 3000 models not Benötgige (speed change for Sensitive, polishing, etc.)
The Oral-B 500 model I could also try, this was me a little too "lashing"
What is there to mention, she does what she does best, brushing and the really good.
I brush always about 3 minutes, 2 times a day, and get for whatsoever a praise by the dentist, even if he deserves nothing about it! ;)
