Having owned and used the device I can attest to that. It was hard to get it to work reliably, and it certainly couldn't handle either small finely detailed items or bigger spaces like whole rooms.

It would do part of a room fine and then lose tracking and never be able to re-establish tracking and you would have to start all over again.

The V2 (Structure Core) has a built in IMU and is much better at keeping tracking. The quality of the USB link between the sensor and the computer also makes a big difference. (not an expert in this particular area) but iirc USB is like TCP in that if a packet is missing or corrupted it'll ask for it to be resent, it seems like the Structure sensors are quite sensitive to this and missing more then a few frames leads to alignment issues. That being said I wouldn't call the experience user friendly on any level, their software is really really bad too, I've had to write some tools to modify their save files so that I can rotate the reconstruction area because that's not a feature of the software. Definitely strongly dis-recommend buying one.
