The ease with which it integrates into our software is great! It's very intuitive for users as well; I haven't found anything that wasn’t straightforward or didn”™ know how simple/easy something was before using this product (or any other). We have been able use xlims in conjunction wth another vendor we also used at previous jobs who had their own version called "FlexiViewer". There were some issues where Flexiviewers client would crash when switching between viewing screens but not so much here - maybe just because there are fewer things?
