The set came with two convex mirrors, instead of one concave and one convex.

The ad states these are 2.9 diameter. They're only 2"

Good optical quality, nice range of focal points for the experimenter, a nice way to demonstrate the focal points of parabolic mirrors

I wish they had a set of 6 concave or 6 convex as well in their inventory. I teach optics to grade 10 students and have them capture the real images through an optical bench set-up. Convex mirrors are not as useful for us as they only produce virtual images.The mirrors seem fairly strong and should endure and last through the mild crashes and falls expected. So durability is the only issue that may arise. The mirrors are awesome otherwise. Good quality images produced.

My only issue is that the mirror edges chip easily. Otherwise this high school physics teacher likes the selection of mirrors, especially for the price.

Excellent for children to understand that mirrors do invert images and magnify and minify and that science is not like a magic trick but a legitimate field worth thinking about, not that it’s profitable to think about mirrors but since it’s not too expensive it’s reasonable to purchase.

Problem-free, start to finish.
