I love how easy it was to learn, so much that my husband learned too! It's very user friendly but still has all of those advanced features you need as well (which are not always intuitive).
The fact there were SO many errors in our simulations at first makes me wonder if we're doing something wrong with what data they have us use; however after further investigation into this issue myself - nothing came up other than being patient until everything started working correctly again!! Once learning takes place though-it really does pay off big time. We've been able to create more realistic models which helps save lots or money down line by saving trial sizes/times needed etc.- This also allows better decision making when talking about new drug development ideas from an economic standpoint due its accuracy compared against previous simulators out their available now online like PESTiCALc & VSSIMulator Pro /V2M.
