The customer support of this product has been outstanding! I have never seen such great service from any vendor in my entire career, including Microsoft products that cost many times as much per month for less features than Millenium offers.
It was easy to set up our new system with their team's help - they were very patient throughout all stages (including troubleshooting) so we could get things working quickly without having to spend days or weeks learning how it works by trial-and-error ourselves. They also helped us customize some aspects like adding additional fields/options when creating an account profile page which saved time later down the road since there wasn't anything else out there quite meeting those needs at the same price point.
