Pros:Quality Lenses, Strong Construction
"Is great to use but difficult to change from 20x to 400x. The manufacturer has a problem. Had to use pliers on the first one and broke a fingernail and the replacement was better but 400 x was still difficult to use and focus. Not like the one demonstrated at the CES in Las Vegas in January. "

Anyone else have this?
