Review
What this product is
Written after the analysis, from the same sources the score is built on: the manufacturer's documentation, available studies and verified owner feedback.
The cost-of-ownership winner, and a useful demonstration that the drugstore shelf is not a compromise.
Stiftung Warentest graded it 2.4 "gut" in 2025, up from 3.0 "befriedigend" in 2023 — a genuine improvement between generations. ETM Testmagazin scored it 84.3% "gut" and made it their price-performance winner in 2020.
The economics are the point. At €34.99 with heads at €2.65 — €5.29 for two, stocked in every Rossmann store — the five-year total is about €88. That is €26 less than the Oral-B Pro 3, €106 less than the iO 3, and €437 less than the Curaprox.
It is a sonic brush at 31,000 movements per minute with four modes (Normal, Soft, Massage, Brightening) and a timer with an interval pacer.
Two real compromises. There is no pressure sensor — the one hardware feature with supporting trial evidence, from a 36-month randomised study in people with existing recession. And charging takes about ten hours for roughly 50 minutes of use, or about twelve days of brushing. The long charge and short runtime suggest a nickel-metal-hydride rather than lithium cell, though the chemistry is not stated and that is our inference.
Stiftung Warentest's verdict on the four modes was "Großes Bedienspektrum, aber nur durchschnittliche Putzleistung" — plenty of settings, average cleaning. Which is precisely the point about mode counts.
Buy it if the budget is genuinely tight, or as a second brush. The €12.50 more for an Oral-B Pro 3 buys you a pressure sensor and oscillating-rotating action, and that is the upgrade we would make first.

FAQ
Frequently asked questions
Does the missing pressure sensor matter?
It is the one hardware feature with supporting trial evidence. A 36-month randomised study of 87 people with existing recession of 2 mm or more found powered brushing with a visual pressure sensor produced -0.10 mm of recession change against +0.17 mm for manual brushing, with 10.6% of sites worsening by 1 mm or more against 25.5%. Note that was powered-versus-manual, not sensor-versus-no-sensor — no trial has isolated the sensor itself. If you brush hard or already have recession, spend the extra €12.50 on the Oral-B Pro 3.
