- How does the 4100 differ from the 5100 and 6100?
- The 4100 has one cleaning mode and no travel case. The 5100 adds a second mode and a case, and the 6100 adds more modes and a pressure-sensor display. Cleaning action is the same across them.
- Does it work with standard Sonicare brush heads?
- Yes. It takes the same click-on heads as other Sonicare handles, including plaque-control and gum-care heads.
- How long does the battery last per charge?
- Philips rates it for about two weeks of twice-daily brushing. Owners often report needing to charge sooner, so expect to top it up regularly.
- Is it good for people with sensitive gums?
- The single mode is gentle enough for most, and the pressure sensor helps prevent over-brushing. If you need a dedicated gum-care or sensitive mode, a higher model is a better fit.
- What is in the box?
- The handle, one brush head, and a charging stand. A travel case is not included.
- Is it worth it over a cheaper battery toothbrush?
- Yes for most people. You get sonic cleaning, a timer and a pressure sensor, which cheap battery brushes usually lack.
