iO Series 2 Oplaadbare Elektrische Tandenborstel Starterskit, Nachtzwart

The color-fade indicator on the brush head is such a simple idea, but it's already made me notice when I actually need to swap instead of guessing. The dark finish hides toothpaste splatter way better than my old white brush, which is a small win every morning. Battery's been solid for two weeks on

The charging base is magnetic and clicks into place easily, so it's actually pleasant to set it down every morning. The rubber grip on the handle is subtle but makes a real difference when my hands are wet. It's been three weeks and I'm still on the first charge, which is way better than my old one.

The color-fading indicator on the brush head is such a smart touch—it’s already made me pay more attention to when I should swap it out. Charging was quick and the black finish looks sleek on my counter.
