Overview

Description

The Oral-B iO Series 9 pairs a magnetic, micro-vibrating brush head with linear magnetic drive technology for a smoother, gentler brushing motion compared to traditional oscillating-rotating brushes, while still delivering thorough plaque removal. A color-coded smart pressure sensor lights up green, yellow, or red on the handle to indicate ideal, acceptable, or excessive brushing pressure, helping prevent gum damage from brushing too hard. The companion app uses the phone camera during brushing to provide an AI-powered 3D mouth map showing which areas were missed or need more attention, turning brushing into a more guided, data-driven routine.

The Renpho Eyeris 1 Eye Massager combines gentle heated compression with built-in Bluetooth speakers, delivering a calming massage and soothing music directly to your eyes. Its lightweight, ergonomic design fits comfortably around the eye area, making it ideal for short breaks or longer relaxation sessions. With multiple intensity levels, a rechargeable battery, and quiet operation, the device helps reduce eye strain, dry-eye discomfort, and fatigue caused by screen time or lack of sleep. Simply pair it with your favorite playlist and enjoy a spa-like experience at home, in the office, or while traveling.

Decent but has rough edges

Oral-B iO Series 9 is solid overall, though it's not perfect. On the plus side, genuinely useful real-time pressure feedback. That said, app features require a smartphone, which held us back from rating it higher.
