Pebblebee’s Halo watches my back and my belongings

I live in a part of Los Angeles where I feel safer bringing pepper spray on walks. The problem is, I don't always remember to bring it with me, and it's not legal to carry it everywhere I go. Pebblebee's $59.

99 Halo Bluetooth tracker surprised me by being a suitable replacement because it doubles as a siren-equipped personal safety device, and I can bring it anywhere.
