presentation/packaging is good. The product has very good RF sensitivity, but this can be a problem in today's crowded RF environment with so many sources of RF noise. Make sure you turn off any sources that may generate radio signals. This may not be possible if you live in the building as you cannot control your neighbor's devices. You need to adjust the sensitivity or you might go crazy with the device's continuous beeping. I don't understand how the smart mode works: when an alert occurs in this mode, 1, 2 or even 4 lines light up. Display watch face. About HF band:
