What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it
Grades: Each review's own score is converted to 1–10; without one, we grade the review ourselves. Big test sites count more, short reviews half as much as full tests. A video review counts half.
Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.2 for now.

Third-party reviews

What customers like about E FUN NextOne

  • Functional touch panel navigation with a dedicated back button
  • Comprehensive notification support for calls, texts, and third-party apps
  • Multi-functional tools including a smartphone camera remote and music playback control
  • Lightweight and comfortable design suitable for continuous wear
  • Budget-friendly price point for an entry-level activity tracker

What customers don't like about E FUN NextOne

  • Screen visibility issues, particularly poor viewing angles from the side
  • Relatively short battery life, typically lasting only 2 to 5 days
  • Build quality feels noticeably plastic and less premium than competitors
  • Complex setup on Android requiring three separate apps to view all data
  • Lack of advanced sensors such as built-in GPS or altimeter for elevation tracking
  • Limited water resistance, often rated as only sweat-resistant rather than waterproof

Verdict

The E Fun NextOne is a budget-oriented fitness tracker and smartwatch featuring a 1.5-inch to 1.8-inch OLED or LCD touchscreen, integrated heart rate monitoring, and IP54 or IP68 water resistance. Key technical specifications include a 50mAh to 300mAh battery offering 2 to 7 days of life, 128MB to 512MB of RAM, and 4GB of onboard storage for music and data. Its main characteristics focus on comprehensive health tracking—including steps, distance, calories, SpO2, and sleep quality—complemented by smartphone integration for notifications, call control, and a camera remote. The primary pros are its affordable price point, built-in microphone for voice features, and a silent smart alarm that uses sleep data to wake users at optimal times. However, notable cons include its older Bluetooth 2.0 connectivity in earlier models, a display that can be difficult to view from sharp angles, and a lack of built-in GPS, requiring a tethered smartphone connection for route mapping.
