I like that it's easy to use, not too complicated but has all of what we need without being overbearing or overwhelming when needed! It also syncs up with our Google Calendar so as soon as someone opens their email they can see any new items for them right away if assigned by me in my calendar view (as well!). We have used this product since 2013 and there is nothing bad about using Hillo from start until now - no problems encountered yet!! The only thing would be having more options available such filters/columns etc., however those are easily added via an option within each board once created rather than needing additional software which could potentially cost money depending upon how much data needs filtered through per day versus just logging into treelo itself every time. So far everything works great together seamlessly allowing us to keep everyone informed throughout out team regarding tasks going forward along other important dates &.
