I like that it was easy for my students (and myself) when using this software, because there are many different ways in which you do things! It is not intuitive at all - if someone doesn't know how an instrument works or what they're looking up online then searching through menus/options may take longer than necessary; however once one does get used with them everything becomes much easier! The best thing about openlab though has been its reliability over time-it hasn't crashed since we first started doing homework assignments via computer last year!! As such, our class never had any problems completing work as expected during exams etc.; so no complaints here.
