Review on SITERLINK Detector Battery Photoelectric Silence Safety & Security by Evan Burnside

BUYER WARNING! I bought a set of these units as extra units in case our main OneLink system fails. For the price I wasn't expecting much but I expected them to at least work. 2 out of 4 alarms didn't even work out of the box. Of the two that worked, only one worked after testing them less than 5 times. A security risk, of course. Companies should be ashamed of making such an important life-saving product with so little attention or quality control. DO NOT rely on these alarms to protect your loved ones! Because of the unforgivably poor quality of this product, someone can lose someone close to them. Threw them straight in the trash and went to the computer to try and tell a potential buyer about it.
