What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Fitbit Charge 6
Three whitelisted testers (DC Rainmaker, TechRadar, Tom's Guide) field-tested the exact Charge 6. All praise sleep tracking and improved heart-rate accuracy at a low price, but the built-in GPS is the recurring flaw: reliable only when the strap is worn loose, which then hurts HR. Battery landed near six days. (3 sourced reviews, 3 lab-tested.)
Praised: Above-average sleep tracking, close to Oura-ring reference; Heart-rate accuracy genuinely improved over the Charge 5; Feature-packed (ECG, Google Wallet/Maps, HR broadcast) at a low $159 price.
Flagged: Built-in GPS drops out / won't lock when strap is worn snug; Tightness trade-off: loosening for GPS degrades heart-rate accuracy; Best HR features and advanced sleep data locked behind Fitbit Premium.
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, 2 lab-tested.)
Praised: Good AMOLED display / panel quality; Long battery life for the price; 120 sport/activity modes at a sub-$50 price.
Flagged: No built-in GPS (relies on paired phone); Large heart-rate deviations during exercise (up to 39 bpm); Amazon Alexa is slow and poorly implemented.
