The Kieslect Ks3 (ks3) Smart Calling Watch in Black arrived on my desk promising a feature-rich experience at a competitive price point. Over the past few weeks, I’ve put it through its paces, testing its calling capabilities, fitness tracking accuracy, and overall usability. This review details my findings, offering a balanced perspective on its strengths and weaknesses.

The Ks3 boasts a sleek, minimalist design that I found surprisingly comfortable to wear throughout the day. The touchscreen is responsive, and the interface is intuitive, making navigation a breeze. Key features include built-in GPS for accurate workout tracking, heart rate monitoring, blood oxygen saturation (SpO2) measurement, and of course, the ability to make and receive calls directly from your wrist. The watch also supports various sports modes and offers customizable watch faces, allowing you to personalize your experience.

Notification management is efficient, with clear alerts for incoming calls, messages, and app notifications. I particularly appreciated the ability to reply to messages with pre-set quick responses. While not a fully fledged smartphone replacement, the Ks3 provides a convenient way to stay connected on the go.

During my testing, the GPS accuracy was impressive, closely matching my phone’s GPS readings during outdoor runs. Heart rate monitoring was consistently reliable, and the SpO2 sensor provided readings that were comparable to other devices I’ve tested. Battery life was a highlight – I easily managed to get a full two days of use with moderate activity and notification usage before requiring a recharge. This was greatly appreciated and surpassed my initial expectations. However, with intensive usage, such as continuous GPS tracking, the battery life dipped down to a day and a half, which is still acceptable for a device of this type.

The call quality was clear on both ends during my testing, though the speaker volume could be slightly improved for louder environments. The microphone picked up my voice clearly in most situations.

Pros:

• Long battery life
• Accurate GPS and heart rate tracking
• Clear call quality
• Comfortable design
• Responsive touchscreen

Cons:

• Speaker volume could be improved
• Some minor lag occasionally experienced in the interface

The Kieslect Ks3 (ks3) offers excellent value for its price. While it has a few minor drawbacks, its strong performance in key areas like battery life, GPS accuracy, and call quality makes it a compelling option for those seeking a versatile and affordable smart calling watch. I would confidently recommend the Kieslect Ks3 to anyone looking for a reliable everyday smartwatch with some extra features.
