I have adjusted a few and many of other EC products over the years. PROS Not bad controllers, pretty intuitive to get into( almost a merge of ideas between MCE and Smartrise), runs fairly well after installing. CONS..lose the assignment of Fire service to a hall node, use the M1000 drive instead of the L1000 ( tricky gain adjustments to get rid of a few tracking spots) , Lousy documentation (mostly because they are too lazy to print a decent complete manual) They have a startup guide which is ok, but they should document every parameter they have at least via a pdf download. The controller is pretty easy to work on, but if they really expect to be serious competition to MCE, they need to go the extra mile with support and documentation. Tech support is ok but like everyone else, they have guys that will waste your time. They had some serious software bugs, but maybe now they have fixed that.
