The fact that they have anything endorsed by American Rescue Team International (ARTI) eliminates any credibility this business might have. ARTI is operaed by a fraudster whose advice is dangerous to the American public, and who has been denounced by every legitimate search and rescue organization as well as fire departments across the nation. I stopped shopping the site as soon as I saw the "earthquake detector" (really?) endorsed by ARTI. Please. Ignore all advice by ARTI, Douglas Kopp and anything having to do with his Triangle of Life. Listen to the true experts - take cover.
