What do you want to know? Been working with them for 20 years.

These scanners have a resolution of about 0.1 mm the accuracy is 0.05mm. So it would work "okay ish," on a larger bust. There are settings to try and get more detail but it will not pick up details that we see in figures. Belts, pockets on clothes, etc, will wash out and blend together. They seem to be trying for smooth surfaces in their algorithm when they convert the scan into triangles. It can take a lot of work in down stream software to get back what you want. Now if you want to start a business and have things like you see in the picture from Mirofsoft then this will work so long as you have an editing software to use afterwards to clean up and edit the scan data, which will be triangles, lots and lots of triangles.
So here is something that no-one tells customers when they buy a scanner. Scanners do not capture sharp edges. Never ever!!! There will always be a rounded over fillet on a sharp edge. The reason being is when the scanner projects out the laser line (most popular scanner). There are actual about 10,000 points into the projected line, they are so close that it looks like a line to our eyes. Each one of these points of light bounce back to the camera (over simplified description). The problem is the light on the sharp edge is either one or two points or none at all as they do not bounce back to the camera. So when the software starts connecting points to create triangles there is nothing there so it attaches to the points that are on the other side of the edge. This produces a rounded over fillet edge. So if you have a laser that has 60,000 points in the laser line ($100k US), you will get the same results but the fillet will be much smaller. The editing software for these models (polygonal i.e. triangles) have algorithms that can bring back sharp edges. So you need to buy a post editing software for your scanner and learn how to use it. I liken it to " you have to buy a paint brush, after you buy a figure and jars of paint to move forward. "
Here is a link you can see what I describe, scroll about half way down in the article to the small detail and sharp geometry section and watch the pictures of scans of a hole saw and a 3d model of a cathedral.

I hope this helps and again ask away on any other questions.
