Bought this pack about a year ago and I'd be cautious. Two issues:

1) the battery life isn't what I hoped for - I have to charge the batteries once or twice every week brushing twice a day. The battery has run out while away on work trips. Furthermore it takes longer to charge than I would have imagined.

2) there is a real problem with bacteria build up underneath brush heads and where the head connects to the toothbrush. It gets very nasty and not hygienic. Google it!

Any idea if the battery life is better on the series 6 or 7?
