Details:

Focus Z knobs work properly. Eyepieces show an image even if basic paper used. If you want to see other microscopes I have just shoot me a message. I don't know anything about microscopes never used them before.

Stage moves in X/Y directions. All I can tell is you that it powers on. I have several different microscopes. I checked to see if Power works light turns on.

I ll make sure to bubble wrap before sending.
