Five modes, a hard case and real-time app tracking of where you brush make up the iO5's pitch.

Laifen's brush both vibrates and swings its head through 60 degrees, a hybrid of the sonic and oscillating approaches.

- Battery life goes unpublished, as on every iO above the iO2
- The iO6 adds a confirmed display for $40 more, which squeezes this model
Laifen Wave Pro: what it gives up
- Laifen's page contradicts itself on intensity levels
- Travel case sold separately
- Not named on the ADA listing, which covers the original Wave
