I'm happy to let you know that free trials are now available for Invisible accounts. If you're sitting on the fence as to what sort of account would be best for you, feel free to test drive the Invisible account in addition to the Premium account.
Creating a free trial account requires no billing information and there is no obligation to purchase. The trial period is 14 days, which gives you enough time to kick the tires and see what it's all about. As usual, if you have any questions at all about your free trial account call or email using the contact info at http://www.wundercounter.com so that I can help you decide what best suits your needs.
