Very good toothbrush. Generally, I was looking to see if I could buy a more expensive one with more modes and features. Fortunately, I didn't fall into the trap and bought this one. It has two modes. The two most basic ones. Even if I had bought a more expensive one, I would still use these two modes. So I think I saved money. The battery lasts for a week with two uses per day. It notifies you every 30 seconds. It also notifies you at the two-minute mark. Personally, I ignore them, as I use it for more than the recommended two minutes by dentists, but for anyone interested, it is a useful function.
