It is very easy to use, not much time was required by my team or myself in order set up our demo project which really helped us understand how this software works with ease! I would highly recommend kleev3d as it has been extremely helpful when creating immersive experiences like we are doing at work currently!! Definitely try out their free trial version first if you want an idea of what they can do but then go ahead take advantage because all that money will be worth every penny once its live.
We have created many VR/AR projects using KleeVtimate including demos & presentations where people could walk around 360 degrees without any lag issues while browsing through content from different points within space.
