Our Testing Experience

We used the Mijia T302 as our daily driver for three weeks before writing this review. Straight out of the box, the pairing process with the charging base was simple — no manual needed. During the first week, the sonic vibration felt noticeably stronger than a standard manual brush, and our teeth felt visibly cleaner within just a few days.

One thing we noticed early on was how quiet the motor is compared to other sonic brushes we’ve tested in the past. It’s not silent, but it won’t wake anyone up if you brush late at night. The battery indicator was accurate throughout our testing period, and after two weeks of twice-daily use, the battery had barely dropped — which lines up with Mijia’s 150-day claim.

The only minor annoyance we ran into was remembering which of the four modes we had left it on, since there’s no display screen to confirm the mode at a glance. Aside from that, the overall experience felt smooth and reliable for daily use.

How to Maintain Your Mijia T302 for Longer Life

• Rinse after every use: Run the brush head under water for a few seconds after brushing to remove leftover toothpaste and debris.

• Replace brush heads every 3 months: Even though four heads are included, dentists recommend swapping heads every 3 months for optimal cleaning.

• Store upright: Keep the toothbrush upright on its base so the brush head can air dry fully between uses.

• Avoid full submersion in hot water: While IPX8 rated, prolonged exposure to hot water can affect the seals over time.

• Charge occasionally even with long battery life: Even though the 150-day battery is impressive, topping up the charge once a month keeps the battery healthy long-term.
