While magnifiers are widely available, this is a good one at a great price. An internal three-LED array fills the field of view with soft, diffused illumination, so you can clearly see whatever it is you are examining, even in dim light. It also has a touch-on mode that lights up the magnifier when you grip it and automatically shuts off when you release. The 2 1/2" diameter glass lens gives a clear, crisp image and is adjustable to provide 1.5X to 2X magnification by simply twisting the anodized aluminum housing.
