Same summary

The Oral-B iO4 Matte Black electric toothbrush is primarily designed for adult users who want more consistent and gentle daily care for their teeth and gums, especially if they prefer a more mechanical brushing sensation. The multi-program rotation-oscillation technology and pressure sensor allow for adjustment based on gum sensitivity and help with proper use, while striking a balance between efficiency, simplicity and oral health protection.

The model is less suited to users who want extremely quiet operation or a minimalist approach without additional smart features. The included carrying case and powerful battery are advantages for those who travel frequently or want greater flexibility in use.
