Our research shows folks appreciate how easy it is to carry around, so whether you're at home or out and about, it's pretty convenient.

Of course, things like interference and where it's placed can affect how it works, but generally, it seems to hold up well within the advertised range.
All in all, with its 25-mile detection capability, the AcuRite 02020 is a practical tool for keeping tabs on lightning, letting you stay ahead of any brewing storms.
