Yea have spoke to them, sent all the defective kit back etc. The faults arnt huge ones, but enough to have customers ringing up saying it isn't working. For example the keypad not connecting to the panel. The ones with problems normally connect 2nd or 3rd try, however if your a customer who has just paid out a wad of cash for new system, you want it to work. As matt said its normally a panel problem.
