It is easy to use, it's intuitive for beginners as well experienced users alike! The interface of this tool makes me feel like I'm not using something that was made by someone else but rather built from scratch with my needs in mind (as an engineer). Sometimes there are bugs which make you want to just give up because they're so frustratingly difficult to fix. But if you stick around long enough - one day things will get better :) That said, we have been able to solve many issues using this software easily without having to resort back to our old methods involving emailing files or making phone calls etc. We've saved time solving problems related to getting feedback about projects being reviewed by other engineers who may be new at their jobs.
