I have been using Retrium for the past one year. I am Scrum Lead for 4 teams and due to licensing limitations, we have been using Retrium for 2 of my teams belonging to 2 different programs. Though I had conducted Retrospectives in various other tools, I found Retrium comparatively useful and user friendly for the following reasons., 1. No Limitation - I can create boards for as many teams as I can if we have license. 2. Customization - Retrium allows me to customize the options I need. As a Scrum Lead, I find customization very useful for my teams. 3. Stages - Retrospectives has various stages along with a stop watch which makes it more interesting. 4. Anonimity - The team members can share their opinion and can still remain anonymous. i.e., It DOESN'T show who is typing what. 5. Action Items - All these years, as a SM, I have captured "What went well" & "What didn't go well" and "Action Items". But we Retrium provides an unique section to highlight the action items. 6. I like the cool colors of the UI.

Retrium comes with great UI. The various features are really helpfull in kepping the track of the action items. Have been using it to analyse the sprint activity.

Super collaborative, keeping feedback anonymous
