Easy to use and offers a multitude of tools to use for panoramic imagery. Their overlay editor is very complex and user friendly. GoThru Navigator and GoThru VR are awesome apps to showcase the tours on VR glasses. Their support is top notch.
There is no downside...The only thing is that they use Google API for publishing on Maps and it depends on Google how the tour is shown.
You have 2 free tours to test the system, you can cancel at any time, but I bet once you try their platform you won't regret!
