Its internal memory feature is a great bonus, as it lets you store data for one training session without needing to connect to a device.

There are a few drawbacks to consider. While it does boast excellent connectivity options, some users may find the initial setup a bit complicated, especially if they are not tech-savvy. Additionally, while the battery life is generally good, users should be aware that frequent use may require regular battery replacements. The strap size is limited to M-XXL, which could be a concern for those outside this range.

There are a few drawbacks to consider. While the connectivity via Bluetooth is effective, it might limit compatibility with some devices, so checking whether it works with your smartphone before purchasing is essential. Additionally, while the heart rate and swimming tracking features are robust, some users might find that it lacks in-depth analytics when compared to more advanced, dedicated swimming monitors. Comfort and fit are generally favorable, with a lightweight design, but some users with larger wrists may find it a bit snug. Lastly, while the built-in Alexa adds convenience, it may not be a critical feature for everyone.

You can monitor your heart rate in real-time or record your session for later review, catering to different preferences. However, while the device is compatible with many platforms, some users might find the lack of built-in display a bit inconvenient, as they need to rely on connected devices to view their stats immediately.
