I like it because its easy for new people in our office who are just learning how to estimate projects, or someone who has been out of work so long they can't use Excel anymore! It's also great since we have an estimating team but everyone doesn't need access at all times due to security concerns & privacy issues with sharing files online as well. We've had some glitches when using during storms where power goes off which causes us problems once back up comes back again after awhile (we're talking about hours). So far no major software/ program changes would be needed if possible without having too many updates from Microsoft each year that could slow down performance even more with older computers not being able to handle newer programs very easily either. As simple as creating sheets within excel then exporting into TRFs format makes this process quick and painless compared with other products such as Procore etc.
