Review (5/5): Keeps my teeth clean
These toothbrushes have lasted for a while. I believe I've had this for at least 3 years. The strength is nice and the settings are great. My teeth feel a lot cleaner after using this. I'm also very happy about the timer function that buzzes after 2 mins of brushing. It helps to make you brush for the recommended time. As far as the battery, after a full charge I can make it last for 3 - 4 days, this is after 3 years so I think that's decent. I usually just keep it plugged in and that's fine.
