What you actually get
The paragraph below is Amazon's own sales copy. We keep it quoted and set apart rather than folded into our text, because marketing prose and a description are not the same thing — and because what it leaves out is as useful as what it claims.

Reading the discount
Amazon publishes a single figure for this configuration — $399.00 — and no separate list price beside it. That removes the usual anchor, and it is the honest reason you will find no percentage anywhere on this page. The specification has to justify the money on its own.
The listing carries an end date of 30 September 2026. Retailers pull pages early and without warning, so read that as the outer edge rather than a promise.
What else the tracker has at this money
The closest tracked listings in wearables are Fitbit Google Air - Screenless Activity Tracker - Berry at $99.99 (Amazon) and Google - Fitbit Air - Screenless Fitness and Health Tracking - Works with Android and iOS - Obsidian - at $99.00 (Amazon). Both undercut it, so the case for paying more has to come from the table below rather than from the price.
These are the nearest listings by price that our tracker currently holds, not a survey of the market. Anything not on sale at one of the six retailers we follow does not appear here at all.
The strongest reason to pick it is the heart rate sensing frequency, which delivers HRV and background readings far more often than typical wearables.
