The magnifying glass is not as described, the diameter is 75mm and 63mm not what might initially be regarded as an advantage. However, they increased max. However, factor 2 and not factor 3. To box is 75mm dia., On a white sticker Ø63mm magnifying glass, 3x magnification. Sorry, that is a lie smooth. Furthermore, the glass quality is so bad - that the magnifying glass is useless for my engineering activity. I need to order texts and numbers of large drawings printed reduced to DINA4, can read it. I possess even a 50mm lens with 2x magnification, which produces by its good quality glass clear magnifying images, however, this magnifier delivers unclear images. So she goes - made in China - immediately returned.
