Buy the Philips Sonicare 4100.
It is the toothbrush with decades of proof behind it, not a spec sheet full of unverified numbers.

Five reasons
1. Proven sonic tech beats unverified RPM claims
Sonicare's sonic vibration is backed by decades of dental use and widely documented clinical results. GRAUICI's 4500 to 8800 RPM oscillating motor is a marketing number with no independent testing behind it.
2. Built to outlast the GRAUICI by years, not months
Owners report Sonicare handles lasting around 5 years of daily use, a track record built over the whole Sonicare line. GRAUICI is a newer, unestablished brand carrying inconsistent star ratings (3.9 vs 3.6) across its own listings, a real red flag on build quality.
3. Philips actually answers when it breaks
Philips backs the 4100 with a documented 2-year warranty and a track record of Consumer Care responding to defective units. GRAUICI, a generic reseller brand, shows no visible warranty or support history if your unit dies early.
4. A timer that actually trains you to brush right
The 4100's 2-minute guided timer with quadrant pacing nudges you to cover every part of your mouth evenly, exactly what dentists push for. GRAUICI's listing shows speed modes and a pressure sensor but nothing that paces your brushing time.
5. Yes it is cheaper. Buy the Sonicare anyway.
GRAUICI is 5 dollars cheaper and bundles 8 brush heads with a 50-day battery, real numbers on paper. But Sonicare's 14 days already covers two weeks unattended, plenty for daily use, and unproven budget electric brushes have a well known habit of failing well under a year, erasing any savings.
