The best thing about simIO for me personally, it's ease of use! It was easy to get started using this program because I don't have programming experience at all - so that helped out with getting my feet wet in order to learn more powerful programs later down the road as well.
As far as what i dislike most? Nothing really comes up until you start looking around trying things yourself but if there are any problems or bugs please let us know right away!! So glad we chose simIO over other similar products available online (we looked into several). We were able to figure everything out ourselves without having someone else come along side help/advise when needed which saved money overall since no one had time off from their jobs during our training phase.
