I recently bought the child locator from Brickhouse security. It is advertised to help you find your child if they get lost. It doesn't. I tested it out on my husband at the mall. We split up and I tried to find him using the locator. It didn't work. It is advertised to work within a 600 ft radius. It doesn't work out of a 2 ft radius. It was a big hassel to return it, and then they charged me $50 to return it. I am so upset.
