Not bad for the price, pretty useful - Celestron LCD Handheld Digital Microscope

It took some guesswork to figure out which way the batteries went in, it wasn't obvious and the directions didn't say. But I was pleasantly surprised by the image quality. I haven't used the video, just still images. The problem I have encountered is that sometimes I want to look closely at the surface of objects that may be on the order of 5 mm - 10 mm diameter, and they might not fit under the lens. So I have to hold the unit, which doesn't work as well.
Pros: Compact, good images if you're careful
Cons: Delicate battery compartment door, instructions lacking clarity, difficult to view larger objects
