I have not run this on my own store yet, but I know the team behind it and I have been watching them build.
The idea is right. Product photos only get you so far. Letting someone spin a product around and look at it from every angle is the closest thing to picking it up in a shop. For a lot of stores that is the gap between a sale and a return.
What I like most is how simple they kept it. Upload a .glb, set the lighting and camera, preview, publish. No theme editing, no developer needed. That is much harder to build than it looks.
Solid first launch from a team that clearly cares about the details.
