It is pretty simple UI, and everything is there, no hidden feature. I found nothing to dislike about TrialRun. It is pretty affordable, so we bought one. The UI is intuitive and easy to learn. We tested with 5 different customers which we found in TrialRun. I like how easy it was for our team to set up an A/B test with a variety of content options.
Our marketing teams were able to quickly build out new campaigns, assign them to different tests, and then collect data to make informed decisions.
