Good microscope, great value
Great little microscope-optical quality is very good. A few minor issues: With its small stage you may find it difficult to look at the center of larger PCBs. The optical stack does not end with a threaded connection, so you have to use provided 2-sided tape ring to attach filter to stack. Instructions were just ok- 4 adhesive dots needed to attach the ABS base were not provided. MicroSD card slot reader is a bit too recessed from the case’s opening — you may need to use a small tool to push the memory card in fully (clicks in place). Finally, I wish there were a way to control the ring lights’ brightness. These are all minor issues- this is a good microscope!
