I just wanted to let you know how helpful and impressive I find 4Matrix. It is extremely useful and very well priced in comparison to other products I have either used or been presented. In addition to a great product, the staff I speak to are always highly professional, quick to respond and extremely resourceful. There have been a number of times where they have sent me over resources, implemented suggestions I have made into the product or had in depth discussions about your implementation of particular measures. Keep up the good work!
