"It has been years since we had a home security vendor and professional monitoring. Finally got around to re-adding security to our list of home services. It was more than time. Tried a package from amazon but had issues from the start. Ended up returning it. ADT ended up saving the day. We didn’t want to waste any more time with cheap security products. ADT had been the perfect fit for what we were looking for and needing."
