I use high quality lens for several hobby purposes. This is a poor quality product falsely described, but it is a great price for what is delivered.

The low quality glass optics magnify about 10-power, maybe a bit more. It's perfectly fine for casual use, an environment where one would not want to take an expensive lens, or certainly for a child.

If it were accurately described by the seller, this would rate five stars! Since it described falsely: "This extremely powerful Jeweler's Loupe is 3 times more powerful than the average (10X) louple", I have to give a low rating. Liar, liar, pants on fire.

Still a great value though, just know what you're getting.

FYI. If you are really looking the highest quality lens, make certain it is a "Hastings Triplet" which will provide chromatic and distortion correction. These are quite expensive and are only available in smaller sizes, so be sure to read the specifications carefully for the lens size and field of view.
