Comments about Celestron Celestron Digital & Optical Microscope, 2000x Power, LED Illuminated, with 2MP Camera & USB Cable:
I fixed it.I found one extra nut inside the revolving unit and removed it. I guess it might be inserted by chance during assembling this unit.Another problem is freely moving lens power indicating ring. I couldn't fix it.
