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!

Series 7 and up has the fast charging under 3 hours. Supposedly battery life is 14 days, I've gone multiple weeks without charging my iO7. My iO7 also has a screen that tells you the battery life. For the bacteria build up/general cleaning I always use an ultrasonic cleaner and it easily manages cleaning.

I'm comparing this deal vs Sonicare 6400 for $29.96 on kohls.
Sonicare 6400 will be $60 for 2
Costco pack Includes 2 Handles, 4 Brush Heads, 2 Charging Stations. So there are 2 additional heads.
So the price difference is not a whole lot, but Sonicare is slightly better priced even if we include the cost of extra heads.
Thoughts?
