## What reviewers say

**Amazfit Band 7** — Two whitelisted hands-on reviews cover this exact model and both survived verification: Notebookcheck (lab-measured, 2023) and Tom's Guide (2024). Both praise the AMOLED display and long battery life for a sub-$50 tracker with 120 sport modes, and both flag the lack of built-in GPS. Notebookcheck additionally lab-flags large exercise heart-rate errors and a slow, poorly implemented Alexa; Tom's Guide flags paywalled Zepp premium reports and a strap that can come undone. (2 sourced reviews.)
