We needed to share realtime rendered scene with clients and this tool is useful.
Its taken a while to understand the software but its very powerful compared to other products in its class such as Marmoset Toolbag , Sketchfab or Unreal engine.
No install requires and I can share full 3d scenes with a link. You can also embed on your website.
Not to much in the way of docs but then again its not to complicated to find out how it works if you spend some time in the UI. Their support is also very good.
It's free, for starters, it has online training, and support is there to help you when you ask for assistance.
It can sometimes freeze on you while designing.
