فرشاة أسنان كهربائية سينسونيك رمادية – رمادي (STW-03W027)

The stain removal mode actually made a visible difference on my coffee-stained back teeth within the first week, which I didn't expect. The gum care setting feels gentler and less jarring than my old brush, and the battery has lasted me over two weeks so far.

The vibration feedback when switching between Clean, Stain Removal, and Gum Care is surprisingly intuitive—I know exactly which mode I’m in without squinting at the button. My teeth feel noticeably smoother at the gumline after a week, and the battery hasn’t dropped below half yet.

I’ve had mine for about two weeks and the stain removal mode genuinely made my teeth feel smoother by day three. The handle’s grip is comfortable even when my hands are wet, and the charge has lasted the whole time so far.
