The ease of use is one thing that I love about this software! It's so simple for my team members who are not as tech savvy with computers or even using an app like Microsoft Excel/Powerpoint etc., it makes their job easier than ever before since they can quickly create estimates without needing any training at all (even if its just clicking "OK"!).
There really isn't anything bad i've come across yet but there could be some minor quirks here &there which aren't big issues tho'. But overall quick eye has been great when creating our work orders - no more having multiple spreadsheets in order track different aspects throughout projects we're working on!!
