I have been using my NITERunner for a few months and did not think I would ever have a use for the Alarm. I run most evenings on the outskirts of town on quiet roads with small farms and large properties. Today I was running along in a daydream when a large, very aggressive, growling, snarling dog suddenly ran alongside me. Thankfully it was behind a low fence, but I was worried it was going to jump the fence so I pressed the alarm. The dog put its tail between its legs and ran off. I was very relieved and thought you might like to know another use for your excellent product.
