Lynx fitted my alarm 14 months ago and I left a 5 star review at the time. They came and serviced the system a couple of months ago and replaced all the batteries, again very reasonably priced service and engineer came on time and gave great service. Recently I had a couple of false alarms on the system and the panel sounder was not working correctly, something was obviously wrong. I called Lynx at 8am, got a callback from on call engineer within 5 mins, another call from the office within 30 mins who arranged an engineer visit same day. Turns out the panel had developed a fault that meant it had to be replaced completely. Lynx were great, without any hassle they installed a new alarm panel, and despite it being just out of manufacturer warranty period it was done free of charge as they felt it shouldn't have developed a fault (I agree!). So from first reporting a fault, Lynx had attended site, diagnosed the fault, installed new alarm, set it up and left everything working within 6 hrs. Brilliant. This really is a great company that looks after its' customers. I will not look anywhere else for my security needs and wouldn't hesitate to recommend them to anyone else. If you're looking for a reliable, trustworthy and customer focused security company, you've found it!
