The myFirst Fone S3 4G Kids Smartwatch offers a range of features aimed at keeping children safe and connected. With GPS tracking, video calls, and an SOS button, it promises peace of mind for parents. However, user experiences reveal significant drawbacks.

One major issue is the lack of SMS communication. Instead, text messaging is facilitated through the proprietary 'My First Phone' app, which has been described as 'social kryptonite' and difficult to use. Many users reported frustration with the app's functionality, including issues with adding contacts to the whitelist.

Setup instructions are another pain point. Users found them confusing and inadequate, especially when trying to bind multiple devices to parents' phones. The process can be time-consuming and frustrating, leading some to consider giving up altogether.

Battery life is another concern. While advertised as lasting 16 hours with active usage, some users found it fell short of this claim. Additionally, the app's user interface has been criticized for being poorly designed and riddled with language errors.

Despite these issues, some users found the watch functional once set up correctly. Children enjoyed features like texting and voice messaging, and parents appreciated the ability to track their child's location in real-time.

In conclusion, while the myFirst Fone S3 offers useful features for child safety and communication, its poor app design, confusing setup process, and inconsistent battery life may outweigh its benefits for many users.
