Review on Enhanced Vision with Ajax Scientific Concave Mirror Diameter by Ben Barrington
Very good quality - focal length 200mm not 250mm
Bought for physics class. They are very good quality for the money. Much heavier and higher quality than most small convex mirrors. After 3 groups of students used them, we found that the focal length was NOT 25cm as advertised, but closer to 20cm (200mm). It's okay, but you still want to know what you're buying.
Pros
- Easy to use
Cons
- Poor instructions
