AK TOOLS review for DS Shipping Rates Zip Distance

This app is amazing, I have been searching for an app that meets my business requirements as I have a complex shipping rules - none of the expensive app can support, but this app is genius. At a very high level, I want to charge shipping rate based on several inputs, such as specific product tags, post code, product qty (not cart qty), product value (not cart value), insurance rate and express rate. The support team is very responsive, and they deserved a full 5 star rating review. ***Edit #1: I've asked for the clone feature to help with initial setup, and within 15 minutes it was made available and working perfectly, what an amazing team to work with. ***Edit#2: Added Export/Import feature for Back-up/Restore purposes.
