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.

Verdict

The MyKronoz ZeFit4 is a lightweight, 17-gram activity tracker featuring a 1.06-inch TFT color touchscreen with a 160x64 pixel resolution. It is powered by an 80 mAh Li-ion battery that offers up to 5 days of standby time and recharges in approximately 1.5 hours. Key characteristics include IP67 water resistance, a 3-axis accelerometer for tracking steps, distance, and calories, and comprehensive sleep monitoring. Main pros include its slim 9.3mm design, interchangeable bands, and smart features like music control, camera remote, and weather forecasts. However, notable cons include its limited 7-day on-device memory, the lack of a built-in heart rate sensor (available only in the HR version), and a maximum Bluetooth range restricted to approximately 5 meters.
