Co-operative Systems designed a system which was perfect for our needs. Their telephone support system is excellent, and engineers will always call into the office if the problem cannot be rectified over the telephone. We moved offices 3 months ago, and I can only describe the state of our new offices, in the first instance as a bomb site. The Co-op engineers, by way of a miracle, managed to install our system and have us up and running within 2 days.
