I love how easy it was for us as an agency/client team (and non-technical) user in general - no need! The fact you can do everything from one place with multiple devices makes life easier than before when there were so many platforms involved between client / vendor etc., We used banner software previously but never felt like our job got done well enough or efficiently until now where this changed completely due too its easeof use plus all other benefits mentioned above which are great by themselves already :) So far nothing really negative about BANNERWISE itself though if anything could be improved would probably have more features suchas video support maybe even 360 degree rotation option? But overall very satisfied especially since i've been using banners myself over 10 years ago hence why my own experience has helped me understand what clients may find difficult otherwise :).
