This is a great stereo-microscope. The Optics is first class. The 170mm standoff distance is a must for electronic rework with a soldering iron.
The standard illumination system is from another era but once replaced by a powerfull LED source, this Russian creation really shines.
Pros: great 36x at 170mm distance, sf arm is very stable
Cons: lamp of an other era
