Our verdict
Where it wins
- Pressure sensor at a budget price, a feature many brushes under $50 skip
- Philips rates the battery at 14 days per charge, so it travels well
- QuadPacer splits the 2-minute timer into four 30-second sections to pace your brushing
Where it loses
- Replacement C2 brush heads are a recurring cost, a 3-pack was $27.99 at Target when we checked
- No Bluetooth or app features, those start on pricier Sonicare models
- Only one cleaning mode, just two intensity levels to adjust
The 4100 is the sensible entry point into the Sonicare line. You get the timer, pacer, and pressure sensor that matter for daily brushing, and skip the app features most people ignore. If you want brushing data on your phone or multiple cleaning modes, look further up the Sonicare range or at the Oral-B iO series instead.
