As a chef and dad, I'm always cautious about safety gear, and this device has been a solid choice. I bought it for family outings, especially with my kid, and it's proven reliable. The bottom line is, it does what it promises: keeps me on track with steps and provides peace of mind with the emergency feature. I've used it for a couple of weeks now, and it's held up well during my gaming breaks and short hikes. No major issues, just a learning curve. I'd recommend it for anyone looking for a simple, effective tool for outdoor activities.
- Pros: The whistle is LOUD and reassuring in emergencies, and the step counting feels accurate even on rough terrain, which is a huge relief for my hikes. It's durable and lightweight, making it easy to carry without noticing, and the battery lasts a long time between charges.
