10X Close-up Map Magnifier

Pros: For my application (inspecting home-made printed circuit boards), it works perfectly. Magnification level fine for viewing handheld - higher levels introduce problems with shaking

Cons: Fixed focus (no focus adjustment.) My unit is not quite in focus when placed on a surface without lifting it up slightly. All-plastic construction (including lens); therefore perhaps could have been a few cents cheaper

Other: Cheap and cheerful magnifier. No, it's not a microscope, but I've found it to be very useful

Pros: Very good tool for my daily work. I use it for checking registration marks and raster pattern on offset-printed sheets. Very good because have clear plastic bottom and no need for additional lightning.

Cons: No focus adjustment for different eyes. I need to lift it up slightly to have image focused, this makes my work not comfortably.

Other: Can be used in many cases, good for computer boad checking, very good for checking of CPU and RAM contacts, and many more.
