Word of advice.
They're made by Sonima.
Avoid them like the plague. They're 'good enough' for what they are, but they could be better. You get what you pay for, and frankly, these really aren't worth it. Pay a little more, and get DT30s, or just stick with SpaceLas.
All the cheap Chinese scanners are copies of the CamTech 6800HP scanners, and all are crap, except some (ahem, DTs) are less crap than others.
Sadly, Sonima ranks at the bottom of the list. SpaceLas is better value, and they also have better products.
I considered getting a pair, but then I found out Sonima makes them.
Also, if you look at the datasheet, you'll find it isn't actually 40kpps at 20 degrees, or 80kpps at 5 degrees either. They made a mistake, and used the same template for all their galvo sets.
