poor design even worse quality control

The user guide provided is for a different product, the lanyard cannot be attached per the manual or any other way (duct tape may help) the range is 150 feet at best in open air line of sight space. Indoors, through 2 sheet rock walls 30 feet at best. Check the batteries, one was double wrapped, second wrap prevented the unit from working. The unit can only be wall mounted or carried in a pocket, no belt attachment. It has worked 3 times so far but I not confident that it will do so for very long I am keeping all of the packing materials just in case it has to go back.
