The glass on this is pretty good. Magnification and the brightness is also good. However, it can be too bright for many people and there is no adjustment for brightness. Ideally, there should be a switch where alternate LEDs light up. The yellow/orange LEDs work somewhat like a dimmer but not very well. If too much brightness doesn't bother you, it is a great magnifying glass. I am putting a translucent plastic around the lens over the LEDs to subdue the brightness.
