The only complaint I have is that it is hard to hold steady while trying to focus. Everything else is better than I thought I would get.

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. Recommend the 44340 over this.
