Philips Sonicare 2100 Series Sonic electric toothbrush HX3651/13, 14 days battery lifer/Damaged package

Step into your bathroom each morning, and let the Philips Sonicare 2100 Series HX3651/13 transform your routine. With up to 31,000 brush strokes per minute, this sonic electric toothbrush drives fluid deep between teeth and along the gumline, removing up to 3x more plaque than a manual brush. The built-in pressure sensor gently pulses to alert you when you're brushing too hard, protecting your gums and enamel. A 2-minute SmarTimer with QuadPacer ensures you brush evenly across all four quadrants, while the Easy-start program gradually increases power over the first 14 uses for a comfortable introduction. The slim, ergonomic handle is IPX7 waterproof and runs up to 14 days on a single charge via USB-A charger. Includes one C1 ProResults brush head, compatible with all Philips Sonicare click-on heads.
