Smart Key Case for Relay Attack Prevention

As a logistics specialist, I'm always cautious about security, and I expected this to be a simple solution for preventing relay attacks. In reality, it does exactly what it claims: it blocks signals dead, giving me peace of mind when I'm at home or out and about. It's no-nonsense and straightforward, which I appreciate, but I wish it felt a bit sturdier or had some indication that it's working. Overall, it seems to do the job well, and I haven't had any issues with unauthorized access since using it. 😊
- Pros: It seems super effective at blocking all wireless signals, which keeps my car safe from high-tech theft attempts. The case is lightweight and easy to carry in a pocket without adding bulk, and it works instantly with no setup or batteries needed—just drop the key in and it's protected.
