I read the documentation in the marketplace and the developers website. After reading I felt confident that it would work within my projects guidelines. Quickly I found that it would not. Developer will not refund. So read and "try" to ask questions before spending your money.

Sorry about this but the refund rules are so clear. Please read the section "Resolving disputes - asking Envato to help" for more details: https://codecanyon.net/page/customer_refund_policy
