I like that this software does exactly what it says! It merges many files together to make large maps easier/faster than manually doing them one by one (like in ArcGIS). This process can take some time depending upon your internet speed but once you get going its not too bad at all. The only thing i dislike about this program so far are minor errors when merging multiple PDFs into 1 file which results in small lines where they should be merged as well instead of just leaving 2 separate pdf's with no connection between each other. If anyone has any questions or issues please feel free contact me via email if possible otherwise message my phone number will work best since we live fairly close proximity wise also so there isn't much distance barrier here either way haha :) Just try out their demo version first before buying because sometimes people think "this must cost alot" then find themselves paying more money later.
