Written by Augur from the 133 reviews analyzed
These replacement brush heads for electric toothbrushes offer high-performance daily brushing. Users particularly appreciate the clean feeling achieved, noting that teeth feel smooth and perfectly clean after each use.… However, some reservations are expressed regarding the durability of the bristles, which seems to be less than in previous versions. Additionally, some users report a tendency for the brush head to turn yellow quite quickly despite careful rinsing.
