The quote from Mick wasn't the cheapest, however he did give me the option to upgrade my old system which I thought was credible. In the end I did go for a new system which is excellent and easy to use.. I didn't have to pay a penny until the system was fitted and when Lee did fit the system there wasn't any mess and he even took his boots off whilst in the house... Before he went the system was explained fully to my wife and in my opinion you will not get a better Alarm currently..
