I have been a customer of Link Alarms fo r several years. I have remained a customer because of the great customer service and quality of your products. Over several years I have only called Link Alarms once to take a look at a fault with my alarm. The fault was resolved quickly. I receive a yearly reminder when my service is due this is always when it is the best time for me. During my last service I noticed on the van Link Alrms also fitted smoke detector. I enquired about replacing my smoke detector which was over 10 years old. They checked it would be compatible with my alarm before fitting. The smoke detector was fitted I am really happy with my digital smoke detector. There are no pushy sales staff just great customer service.
