ScreenshotMonitor.com offers a fully functional 30-days trial of the Professional version for customers to have adequate opportunity to assess the value of the service prior to purchase. After the trial, the credit card is only charged at the end of your billing period - so you have at least 2 months of free use before the first charge. In addition to that to ensure that you are completely satisfied with our product, we also offer 30 days money back from the time of your purchase to get full refund - no questions asked.
