The main lens of the magnifier is a 2.3X which is perfect for reading, jewelry repair and craftwork. The auxiliary lens is 4X magnification which is great for coins and jewelry inspection, as well as removing splinters. My eyesight is not what it used to be and even with glasses it is sometimes hard to read the small print on contracts or containers. This magnifier has been coming in handy for such things.
I received the magnifier lamp in exchange for testing, evaluation and fair, unbiased review.
