I ordered a GSM device at very short notice (order placed on a Saturday morning) and Control Freq had the item ready for collection on Monday lunchtime. The service was fabulous and the alarm panel was very simple to configure. I had the alarms wired and operational within 2 hours of arriving at my Client's premises and the device has been in 24/7 operation for a fortnight with a single issue. I will definitely be recommending Control Freq to my colleagues. Fantastic.
