I like that it's very intuitive, you don't need any training or experience for using zeBruneer (it works well out off box).
The reporting options are fantastic - we can drill down into our tests so easily as compared against manual testing effort! We have found some reports difficult at times but they've been able improve them quickly over time by listening carefully what users want from their report output etc.. Support team were great when helping us resolve issues too which was appreciated after hours working days without response emails / calls being answered during office hrs! No dislikes really apart maybe just minor nitpicks about UI/UX not looking quite right sometimes especially if zoomed way up!! This has nothing directly related however there may be other software available better suited than zebRunners more complex feature set? Being part automated regression suite allows quick turnaround speed between releases meaning less risk getting new features released sooner rather then later allowing quicker feedback loop back.
