Introduction

The Cosmos Endure PFB36 smartwatch promises a lot: a vibrant AMOLED display, impressive battery life, robust durability, and a plethora of fitness tracking features. But does it deliver on these promises? I’ve been wearing the Cosmos Endure PFB36 for the past several weeks, putting it through its paces in various scenarios, from daily wear to intense workouts. This review will detail my experiences, highlighting both its strengths and weaknesses.

Features

The Cosmos Endure PFB36 boasts an impressive array of features, including its stunning 1.46-inch AMOLED display with a peak brightness of 600 nits – making it easily readable even in direct sunlight. The IP68 water resistance rating provides peace of mind during rain or even short swims (up to 30 minutes). The long-lasting 400mAh battery consistently exceeded my expectations, easily lasting a full week on a single charge with moderate use. The 120+ sports modes cater to a diverse range of fitness activities. Beyond fitness, the smartwatch offers standard features like notifications, Bluetooth calling, heart rate monitoring, blood pressure monitoring, and SpO2 monitoring. The device is comfortably lightweight and the adjustable band fits perfectly.

Performance

The AMOLED display is a standout feature. The colors are vibrant and the text is sharp and crisp. The responsiveness of the touchscreen was consistently reliable. Battery life, as advertised, is exceptional. I easily got through a week without needing to recharge, even with frequent use of the heart rate monitor and notifications. The accuracy of the fitness tracking features was generally good, although it occasionally slightly overestimated distance during runs. The GPS functionality was reliable for most of my runs.

The Bluetooth calling function worked flawlessly during my testing period and the quality was impressive. The built-in sensors for heart rate, blood pressure, and SpO2 provided consistent readings. Although these readings should not be used as a medical device, it was very useful for monitoring my general wellness.

Pros & Cons

• Pros: Vibrant AMOLED display, excellent battery life, IP68 water resistance, wide range of fitness tracking modes, accurate sensors, comfortable design, Bluetooth Calling functionality.
• Cons: Occasional minor inaccuracies in fitness tracking, the notification system can be a little slow at times.

Final Verdict

Overall, the Cosmos Endure PFB36 smartwatch is an excellent device offering great value for its price. The combination of a beautiful display, long battery life, robust build quality, and comprehensive fitness tracking makes it a strong contender in the smartwatch market. While there are minor drawbacks, these are easily overshadowed by its many strengths. I would highly recommend the Cosmos Endure PFB36 to anyone looking for a reliable and feature-rich smartwatch.
