Tuan, the force behind this product is VERY dedicated man behind this product and his customer support is second to none! Fast and Comprehensive (He will help even if the issue has nothing to do with EB!!)
The fact that he is continuously upgrading this module (and paying customers get updates for free for life!) means you are buying a product that will keep upgrading itself ( and paying for itself) as you use it.
Keep up the great work Tuan!!
