Code Blue OA1200 Smoke Detector w/Sidekick 1 oz Unlike heavy powders, Smoke Detector floats freely in the air and doesn't fall straight down. Fumbling in your pocket or backpack will get you busted, but the handy Sidekick keeps Smoke Detector in easy reach at all times. The heavy-duty clip attaches almost anywhere, and the elastic stretch cord and form fitted holster keep it close and secure. Just grab it, check it and release it. Convenient, simple to use and 100% accurate? that's Smoke Detector with Sidekick.
