+ For this purpose it is very good, magnification sufficient to detect the blade and burr existing well and to detect errors.
But:
- Nerviger loose contact with the LED, you must unscrew the thing and the contacts bend it to fix these, which is quite a hassle.
- The microscope is to be placed on a surface and has a wheel to adjust the focus. However, the wheel when you have placed it and achieves focus almost at the stop which is not so great is somehow if you want to examine an uneven surface. Parts thereof can not focus then.
- Extremely cheap processing. While it holds everything together but one has simply to keep you feeling a cheap plastic product in hand.
