I have one, it has been for sale in NL for a week already. I consider to buy another.
It comes with a 3mm and a 6mm collet so it can use dremmel fittings. It has a locking spindle. Speed control is via a wheel, like their angle grinders with speed control, located at the rear by the switch. It is torque-y. Stickout from the body is 38mm. If you wanted to mount it the diameter for the mounting point collar is 39.5mm and the width is 15mm.
Price is amazing. Can't say what the build quality is without taking it apart, but I am impressed already. brushes are easily accessible for replacement (but spares not supplied)
weight is just under 1200g
