Review (5/5): A great toothbrush!
When my previous Oral B power brush finally stopped working (after 7+ years), I definitely was going to buy another one. The old one was great but this newer model is so much better. The speed is much faster, it's quieter, cleans more thoroughly and doesn't irritate your gums, even if you put pressure. The noise changes if you press too hard and also at 30 second intervals to let you know how long to spend in each quadrant of your mouth. My teeth are cleaner and whiter than with the previous model I had, I almost wish it had died sooner so I could buy this one. The battery life is decent, ours get used 4 times a day for about 5 days on one charge. It really provides a dentist like clean if you use it properly and though the replacement brushes can be pricey, I'd consider it worth having a healthy mouth and avoiding expensive and painful dental procedures.
