the oral b professional care 9400 is a fantastic product. the difference between brushing with a manual toothbrush and the oral-b is breath taking. it leaves your teeth feeling smooth incredibly clean. the brush has a built in timer which allows you to spend the correct amount of time on each quarter of your mouth with a built in image also showing you when you are brushing too hard, when the toothbrush head needs replacing and when you are done brushing. the built in time also vibrates to let you know when you need to switch sides and when your brushing is complete. it also comes with a charger that you simply place your tooth brush in, with room for additional brush heads if being used by multiple people. the battery life is long, lasting about 5 days before you notice a significant drop in power. it has 3 different brush settings allowing for every last bit of plaque to be removed.
The Professional Care 9400 is a quality product. The first time I used it I was so surprised how much more effective it is than regular brushing with a manual toothbrush. It comes with a charger than the toothbrush itself sits in. For an electric toothbrush it is not very bluky or heavy.
The best feature is the timer. It lets you brush for around one to three minutes and around every forty seconds tells you when to change sides. This stops overbrushing and makes sure you get a good and proper brush everytime.
Cleaning is easy. Mine came with a spare brushhead so once mine is up, you just pop it off and put the new one on. Not only is cleaning easy, but the system itself is easy to use. The adjustable speeds make sure you don't end up hurting your gums. I normally had it on low to medium settings, which I found is still better than using a manual toothbrush.
Battery wise, it is good enough. If you brush twice a day seven days a week, it will probbaly need charging once a week, which is great considering it has an LCD screen that must suck the life out of it.
For an electric, it is slightly noisy. This and that brush heads do need changing every so often and they are more expensive than buying a manual toothbrush, so it is wise to keep this in mind when purchasing one.
