## Verdict

ElectricTeeth and Health.com mention that it is a very early iO model that lacks the pressure sensor and smart display of later iO brushes, so it is outclassed by the Series 3 and 5.

## For

- Forbes Vetted's best electric toothbrush overall
- Health.com recommends it for gentle brushing with overbrushing protection
- Cheapest way into the iO motor
- Simple feature set is good for longevity

## Against

- No pressure sensor
- No smart display
- Outclassed by newer models
- iO replacement heads carry a real multi-year cost premium

## Flagged as one to avoid

This product entered 1 of 9 runs as one buyers cross-shop but should not buy, rather than as a pick. It is published here rather than dropped.

## What this tier means

- B: Good. A solid choice with real caveats worth knowing.

## How to read this

- Each category is researched in four independent runs, one per lens (expert consensus, value, reliability, community pulse). Every run ranks a board of candidates that deliberately includes products buyers cross-shop but should avoid. Placements score on a ranked ladder (LP), and tiers are derived from LP, so no tier is ever assigned by hand.
- LP is this product's points on its own category ladder. It is comparable within a category and not across categories.
- Link status reports what our pre-publication link check found when it fetched the cited URL. It says nothing about the quality of the review.
- A citation with no usable link is listed rather than dropped, and is excluded from the counted total above.
